I'm starting a project that will automatically solve a tilt-maze (Teeter, for instance) on the Touch Pro 2. Since WM programming is a bit new to me, I'm looking for suggestions and advice on how to deal with some of the development issues.
Here are some details of the intended design/process:
- Open the maze program and lay the phone down on a tilting table
- The program reports the ball position within the maze as X-Y coordinates over bluetooth serial port
- A microcontroller with a bluetooth modem receives the data and determines the desired ball direction using a state-machine/path-planning approach
- The microcontroller uses a gravity-rolling model of the ball dynamics to determine the required tilt angle to move the ball along the desired path
- The microcontroller commands two R/C servos to tilt the table in pitch and roll, tilting the phone and causing the ball to move
- The phone updates the controller with the new position and the loop repeats
Alternatively, the phone itself could compute the control law and simply send servo commands to the MCU. Either way, I love the idea (irony?) that the phone generates commands that move itself to solve a maze on itself.
Much of the hardware work is already done. I built an M&M dispenser maze last year that is a robotic implementation of Teeter/Labyrinth.
Search "Office Maze" on YouTube, video 'kUqRcLjFOUc'
We were/are working on getting computer vision to recognize the position of the M&M within the maze and have it automatically solve itself. For now, I like the idea of solving the maze autonomously on the phone.
I've made a basic app for the TP2 that moves a ball around the screen via button interface, but I am still struggling with access to the accelerometer data. I also have had no luck sending data over the bluetooth serial port.
I've read many useful articles and threads, but so far have not been able to implement these functions. Any suggestions on references or example code that describe how to do either?
I have seen several threads reporting compass issues in this forum. I posted one a few weeks ago as well. I have done some troubleshooting and I have now realized that my compass works fine unless I am in my car. This is very strange because I have had this car for several years and I have gone through several phones and have never had this problem. It's like my car is some kind of Faraday cage!
The symptoms are especially visible in google maps. Apparently they use the compass heading instead of the gps course to determine which way to turn the map. The arrow in the center almost always shows me driving sideways down a road. Also if I use the famous GPS Status app, the compass arrow in the middle never comes close to the actual GPS heading. Specifically, my compass always like to point somewhere to the west. If I am travelling to the east (090), my compass will point somewhere to the west (perhaps 270). But if I am travelling due south (180), the compass may point to something like south west. And if I am travelling to the west, there is a good chance the compass will be in agreement and also show me travelling to the west. Maybe I should alter my driving habits to only drive to the west.
But all of these symptoms go away if I am out of my car. If I go for a walk, the compass is fine. It is so obvious that I can stand outside of my car and get a heading, and then take the phone in my car and get a completely, wildly different heading.
I have tried the compass calibration in the GPS Status app, but that has made no difference.
Are there any engineering key codes that can test the compass, or perhaps change the sensitivity on it or something? Is there anything else I can do other than the compass calibration? Anyone have any idea what in my car might be throwing off the compass in the first place?
Hey guys,
So Ive recently aquired and about to return if its defective, my smartwatch 3. I was certain it can do a standalone GPS, but now im wondering if it cant due to software limitations that hopefuly be patched, or is it actually just a lemon?
Ive installed Wear GPS and it finds 0/0 sattelites, even when the phone GPS is on and nearby the watch, in which case all running apps has GPS on the watch too, as long as the phone's in range..
In the Watch Settings I turned on GPS. makes no difference if its off or on actually, still works if the phone's nearby.
any suggestions?
GPS is working, try Ghostracer or Endomondo. They both work well but Ghostracer is loaded with features.
Sent from my HTC One_M8 using XDA Free mobile app
Just clarifying the GPS should function even when disconnected from the phone, correct? Thanks. Prone.
Yes it works. connected or disconnected from the phone.
but the GPS function itself is still buggy,
more information about the gps issue - find here:
http://forum.xda-developers.com/smartwatch-3/help/erratic-gps-t3088179
Erratic is better than statically dead. Flat line 0 GPS signal as soon as phone is disconnected.. RMA or wait for patch? If I understand than even if I get replacement the GPS function is useless at this stage...? Thanks, Prone
RMA.
because the feature itself works normally. (erratic not dead)
I'll take you guys word's for it then.. Cause sony is either totally lying or totally stupid:
Thank you for contacting Sony Xperia Support.
We are sorry to hear you are experiencing issues with the GPS location services on your SmartWatch 3.
With regards to your inquiry, when your SmartWatch 3 is disconnected from your phone or tablet, you can still use some basic features. Since voice commands no longer work after disconnection, you must tap the screen to navigate your SmartWatch 3 and confirm actions.
In standalone mode, you can still do the following:
•View the time and date.
•Set an alarm.
•Use the stopwatch.
•Use the timer.
•View your agenda for the current day.
•Listen to music saved on your SmartWatch 3 with a connected Bluetooth® headset.
•Keep a record of your outdoor activities.
•View your step count.
•Change the watch face.
•Turn Airplane mode on or off.
Note! Some of the features described above require the download and installation of the relevant applications, for example, a music player app or a fitness training app.
Therefore, unfortunately you cannot use the GPS function when your SmartWatch 3 is disconnected from your phone.
If you are experiencing issues with GPS location, check if the location is turned on on your SmartWatch 3.
To turn on location on SmartWatch 3:
1.Tap the home screen, then swipe upwards.
2.Find and tap Settings > Location.
3.If the location is set to Off, press Location. Then press the green circle with “check” mark to enable Location.
Tips to improve the GPS signal when using SmartWatch 3:
•Remove the main unit from the wrist band and clean away any moisture that has built up around the unit or the wrist band to improve the GPS signal.
•Wear your SmartWatch 3 on the outside of your wrist so that your SmartWatch 3 has the best line of sight with GPS satellites.
•Make sure you have a clear and unobstructed view of the sky. For example, while wearing your SmartWatch 3, make sure that your view is not blocked by trees or tall buildings.
•Before you start to move around, stand still to allow your SmartWatch 3 to pick up a signal from the relevant GPS satellites.
Furthermore, due to the fact that Sony SmartWatch 3 was not officially released on the Israeli market, our official service center in Israel unfortunately cannot provide you with service of the device. We suggest you to contact the original seller for more information.
Should you require any further assistance please contact us again via email at [email protected]. For more information on our products, services and support please visit www.sonymobile.com.
Please be aware that if you do not respond within 7 days of this email your query will be automatically closed. Any further communications will not reach our support and a new query will need to be raised.

Whos bull****ting here? Either way im gunna bother and have no SW3 for a while till it gets RMA'd I suppose.. i actually hoped this is a patch thing.
Sony is totally stupid. I use GhostRacer every day standalone, no problems (and the GPS honestly tracks just fine). Its true that there aren't any real stock apps that use it, but it works offline all the same..
Hi
I have exactly the same problem
Here we are, over a year later, and I'm still having this same problem. Has anyone figured anything out with this? I bought my SW3 refurbished, and didn't realize there was a problem with it until the 30 limited warranty expired. I don't really know what I can do at this point. It's really frustrating, as it seems like too many people have this issue for it to just be a fluke.
Hello,
I'd like to use my SW3 to go for a run (without my phone) then be able to see my time, and look at a map of the route I have ran (using the phone's built in GPS).
This is proving more difficult that I thought it would be.
Google Fit is doing weird things. It does track my route, but it's not very accurate. The map shows points along the route joined up by straight lines so it misses out chunks of the route.
The time is initially accurate, but if I load the app up about half an hour later it randomly adds half an hour on to my run.
Strava only seems to work when I'm near the phone.
Anyone else able to do this? Can anyone recommend a good running app that works with the SW3 that gives accurate times and a decent map of the route?
Thanks in advance!

GhostRacer is what I use. It syncs with RunKeeper, and Strava.
Well. I've been using Ghostracer for a while and it's brilliant - at the end of the run it uploads to Strava and then you can see your run metrics and map - I've just finished my first run with the new MM update and the watch worked perfectly, my run was recorded with fantastic GPS accuracy (it even shows where I had to cross the road and back due to roadworks) as well as streaming music via bluetooth! - very happy with this solution.
Thanks for this. I've downloaded ghostracer and will try it out tomorrow. I've also been reading about the issue where GPS doesn't work if you get a bit sweaty. Apparently the solution is to wear the watch over a sweatband! I'll try ghostracer first and if the GPS is still dropping I'll try the sweatband.
Was thinking of upgrading to a Fitbit Surge when I got the money as it has GPS + HR but have just noticed it doesn't play music without a phone. Do either of you know of a device that does the following all independently of a phone;
1. GPS
2. HR
3. bluetooth music player
4. waterproof (or at least water resistant)
5. sleep tracker
6. Watch (ideally with 'always on' LCD type display option)
maybe I'm just being greedy now...
Thanks again!

I read about the need for a sweatband too, but bought this instead: http://www.amazon.com/ArmorSuit-Mil...&redirect=true&ref_=oh_aui_detailpage_o08_s00.
I've worn it during lots of running, including a half marathon, and have not had any trouble related to sweat.

Thanks for this - think i found the UK version: http://www.amazon.co.uk/dp/B00OBZ6I...TF8&colid=12B0B3JX0K1YK&coliid=I13Z14BVM9XIOI
£20 seems expensive though, can help wondering if a bit of masking tape would do the same job! Might try that first.

I use the SW3 with Bluetooth headphones AND a Bluetooth HR monitor when I'm running and cycling - - I use a MIO Fuse for the heart rate - It was £70 on Amazon last July and has been faultless - I'd check it out to see if it does what you want! - I am also using just the Skinomi screen protector and so far so good. I haven't had any problems with the sweat/GPS drop-out that has been reported!
Strava does work independently from your phone with SW3. There's a beta trial at the moment which I think is open to all, you just need to register on the Strava Support Forum (there's a thread dedicated to it) and they give you access. It may even have been in an update - in your Strava settings on your phone if there is a "wear" option that let's you tick the box "use device GPS" then you can do it. It works seamlessly - I ran the Paris marathon at the weekend with bluetooth streaming of music to my headphones and strava running on my watch and my batttery lasted!
Ghostracer worked for me before the Strava beta, I only went back to Strava as Ghostracer updated and stopped working a few weeks ago.
Sorry I can't post any links but I'm at work. The thread on the Strava support forum is called "Android Wear standalone GPS Tracking" and the second post down is where you can sign up to the beta.
Good luck! Chris

You should jump on the google+ group for ghostracer to sort out your issue. The dev is very active and responsive. https://plus.google.com/communities/108600094791246159447
I have the beta for strava, too, and it doesn't do 5% of what gr does.

Cheers. I had GR and Strava installed on both phone and SW3 but Strava has just mysteriously disappeared form the watch. GR now appears on the watch twice. Weird.
Will try GR at Parkrun tomorrow. Hopefully it will just work!
Thanks!
Thanks - will try GR again, I did post on the G+ thread but didn't seem to see any answers. If it's sorted I'll jump back on it!:good:
Ghost Runner works an absolute treat. Massive improvement on GPS accuracy. Thanks for the tips folks!

Thanks, it was a smart suggestion
Having issues with waze app and GPS. I've always had GPS issues with all of the Note series, so this doesn't surprise me. But this time around it seems like waze is the only one acting oddly. Specifically when I'm on a guided route waze intermittently sees me in a different area, most commonly when I'm on the highway it will see me on a side street running parallel to the highway. So then it thinks I'm off course and routes me back onto the highway or another direction, but I'm still on the highway. Sometimes I think it even sees me traveling a different direction, many times I'll be on the highway and it will want me to do 2 u-turns, changing directions twice but ending up going the same way as before. I also see the arrow icon representing my car on the map will constantly turn as if waze can't tell which direction I'm traveling.
My first thought is faulty GPS. I've ran Google Maps and it seems pretty solid, with none of those errors, but I'll have to test some more. Just wanted to see if anyone else got this? I may switch back to an older APK and try that as well.
No problems here. I noticed the 7's gps is way faster than my note 4 too. It finds my location on a second. My note 4 would take 5 to 10 seconds to lock in
I am having the same issue with Waze on my Note 7. It thinks i have turned onto a side road so it trys to redirect me to the the road im acually on. Its seems to think im about 30 to 50 feet to the right on the screen no matter what direction on the compass i am going.
Sent from my SM-N930P using Tapatalk
I've been having an issue when I'm stopped at the light, and the screen will start to spin around. It's like Waze forgot which way I was going so turns me around & recalculates the route...repeat.
Improvement over my Note 3 which regularly couldn't find a GPS signal or lost it in the middle of driving somewhere.
Were issue
I have been having issues also bit but only with the voice guidance. I get hazard alerts but that's it. Any thoughts on this?
waze always seemed to place me about 50 feet to the right of the road. It spent a lot of time recalculating on/off ramps when it didn't think I was driving through corn fields. I figured it was just a calibration issue with my device and didn't do anything about it before swapping it for a non-exploding phone.
I had no problem with my recalled Note 7. The replacement is messing up with waze. All the symptoms listed above are happening. Ugh
Hmm..that's not good..I still need to get mine replaced...
No GPS issues with Waze on my note 7. I use it daily and mine is a replacement. The only issue im having with Waze is the voice commands. The three finger option and waving just don't do anything! Anyone have an issue with that? I want my one eyed purple monster back!
IDK, I haven't checked on my Note 7 yet, I find this a bit funny though, Most GPS's should be accurate to within something like 5 feet, They are really accurate to within fractions of an inch but the Government and Military makes sure that the firmware on the GPS's for use by the general public are locked out of that level of accuracy. It really is a joke these days.
Do a search and in the search box enter in 2##2 to enable debugging and then enter in ##@rawgps and it will show you what your phone is reporting as the actual raw GPS via a yellow arrow. Send in a debug log on the very bottom of the settings every day. Could be possible that Waze can make adjustments to the note 7. I personally haven't noticed any issues with either phone yet, I do also keep my phone in a case and in a windshield car holder with a good view of the sky. When I ran the app for the first time though I did have to toggle location off and on to get Waze to get a GPS lock.
I returned my replacement unit and got another Note 7. No change. Waze is still showing me taking exits and being on the side road before correcting. Very annoying and the constant recalculate and accompanying chime make it onerous to use. Google maps seem to be fine. I submitted a ticket to waze as well as sending log files. I hope a fix comes soon. I need my alerts when commuting.
I fixed my Wave problems. Apparently when you do the smart switch transfer, it transfers some settings or calibrations maybe. I went into phone settings, application, waze, long press storage, clear cache, clear data. Then Uninstaller and re-download and install waze. Mine has been rock solid since doing this. Hope it works for you too.
