SPP Profile on any ROM for EVO? - EVO 4G Q&A, Help & Troubleshooting

I've built a piece of hardware that allows for communication over bluetooth to a phone, and have tested the hardware as best I can. It uses an LMX9838 module from national semiconductor for bluetooth support. I've been trying for an hour to get the hardware to connect to my EVO but it never shows up in the device list. I can get it to communicate with my laptop, my work blackberry, but not my EVO running 2.2.
I've tried searching for EVO 2.2 and SPP profiles, but can't seem t find much. are any mods supporting SPP? I've seen elsewhere on google that 2.1 may have an old BT stack that does not support SPP, but nothing solid on 2.2 yet.
Hopeing someone here knows better.
Thanks.

Anyone knows which ROM has complete working BT with SPP protocol?

Hi all:
I got lot's ROM to try, but according to the introduction, seems like none of them support Bluetooth SPP protocol which is enabled after Android 2.0. Anyone can give a hint about which ROM potentially support this or must I wait for official release?
Thanks a lot!
Vanillain can support BT
but other like camera,gallery... seem buggy
You mean VillainROM right?
I know it supports BT audio, but seems like it doesn't support file push and SPP communication, at least it fails last time I tried it. Not sure if it's my operation error though
Anybody get success on BT communication by Villain?
Not sure what SPP protocol is, but in Vilian 2.1 I have no problem sending or recieving files with my laptop, connecting with my Satnav to get hands free, or connecting with my BT earpiece for calls.

Evo 4gOTA 2.3.3 Gingerbread bluetooth keyboard support?

hi,
i was under the (possibly wrong) impression that gingerbread natively supported bluetooth keyboards. (bt hid)
im at the moment stuck with the OTA update and cant seem to get my igo bluetooth keyboard to work.
any drivers that i can use with gb + igo keyboard?
regards,
asmd.
As far as I know, the problem has been with Sense (which was not upgraded with the OTA) and not with the version of android. I have used CM7 in the past and the HID profile works great. Maybe someone here who is using a Sense 3.0 Rom can validate if HID keyboards or even Wiimotes will work with the new Sense. My guess is no...
thanks for the reply.
Snap!! anybody know how to get a Igo bluetooth keyboard working with the current evo 4G GB OTA?
regards,
asmd.
My microsoft BT keyboard pairs, but doesn't connect. Same issue I had with froyo. Running Mikg 2.15 rom. When i tried the same with cm7, it pair perfectly. Not a complete deal breaker, but would of been nice. I recall reading previously that HID support had to be part of the BT stack. Whether the BT stack is a function of sense or not, I don't know. Practical testing suggests it is.
I realize this thread became a little bit old, but did anyone ever find a solution here? Or is Sense just totally incapable of working with a BT hid keyboard?
I just this past week got a new mini BT keyboard and was excited about all the prospects of using it. I'm currently on Sense MikG 2.5 and have been for about the last 6-8 months, after about a 6 month run on CM7.
I didn't realize, I guess, that there was such a vast difference in terms of BT HID devices. Anyway, I'd seen reference to an Anthrax kernel, but now see no way of downloading it.
Can anyone help out in that regard? And would the Anthrax kernel solve that issue? I might be looking to use the Anthrax kernel anyway.
I have been working to find a way to get my Igo connected. There was some small progress last night. I've been running sense 3.5. Last night I threw in a se of but hid files. Before it would even pair. Now the keyboard pairs but will not connect. For now I am using an ics rom to be adle to use my mouse. It connects with no problem. On sense 3.5 it pairs and connects. But it disconnects in less than a second
I'm having the same problems I have an LG Bluetooth keyboard and sadly running sense I can never get it to work aosp Roms seem to work fine though

[Q] Bluetooth compatability

I'm thinking of upgrading to this phone, one of the main reasons is that my current device, which has galaxy S guts, is not compatible with most bluetooth devices. I like to use an app called blueputdroid that turns my phone into a universal keyboard as well as an ELM bluetooth device that turns my phone into a dyno along with the torque app for my car.
For some reason the way samsung built the bluetooth makes it not work with a lot of these things, I know it's not the apps or 3rd party devices as I use my old G1 now for it, but would much rather just have my main phone be my one device.
Have any of you tested blueputdroid or any bluetooth devices? If not could someone try out blueputdroid with this phone (it's free in the market) any help would be much appreciated thanx!!
Says it has detected unsupported Bluetooth stack.. Install cyanogen Rom, etc.
Thanks, at least this phone is likely to get cyanogenmod support which will fix the problem my SK sure as hell won't
My GS2 works perfect with my ELM adapter. It worked perfect with my Vibrant too. I've never had a single problem with any bluetooth device on either of them.
I've had a lot of bluetooth problems with both my vibrant and now my GS2. Both work reliably with my wife's mini cooper bluetooth but they both have had problems connecting to the garmin nuvi I use for handsfree in my car (and forget about the A2DP on it).
I tried a lot of roms on my vibrant (incl stock) and they did lots of cool stuff but never made the BT connect reliably. Then I came across this thread: http://forum.xda-developers.com/showthread.php?t=795691
I made the suggested change to /system/etc/bluetooth/audio.conf and voila! I finally have good BT with my vibrant.
So I got my SG2 last week, rooted it and found that it also had the bad settings in /system/etc/bluetooth/audio.conf. However it also lacked BLN (backlight notification) and few other tweaks I've come to love on my vibrant so I flashed juggernaut 2.6. That fixed all the major foibles with the SG2 but it still won't reliably connect to my garmin.
I opened up the filesystem to find that /system/etc/bluetooth/audio.conf is no longer there! Does anyone know where it went?
Apparently I don't have enough posts to ask in the dev forum where juggernaut was posted http://forum.xda-developers.com/showthread.php?t=1322642 so I'm hoping someone will see this plee for help.
thanks
the phone has BT 3.0, but it is backward compatible with BT 2.0 and 1.0 devices
i haven't had any trouble using it with my car deck (streaming audio & phone), my large collection of stereo BT devices, and other BT enabled phones & PCs/Laptops
the remote control feature from the stereo headsets works properly, for fast forward, backward, play, pause, talk, mute, etc
the only thing i have yet need to test BT on is with a BT smart wrist watch

[Q] Bluetooth 4.0 to 3.x DOWNGRADE, possible?

I have a Galaxy Note 2 running Jedi Master 13. Every single thing is awesome about this phone...
EXCEPT:
I have a Lincoln with the new MyLincoln Touch radio. It supports text messaging ONLY with ICS or more specifically, Bluetooth 3.x. The Bluetooth MAP (messaging access profile) is different in 4.0 and thus not supported. Is there any way to downgrade said Bluetooth version?
I only use BT stereo and phone headsets normally, never use file transfers so the 4.0 advantages wouldn't affect me (I hope).
Thanks in advance for the input! :good:

Yes, yes I did. I was in touch with the people that make the MyLincoln Touch device that works with Microsoft Sync. I have the newest version, which supports up to Android 4.1.1 and the Bluetooth 3.0 software, which has advanced compatibility with MAP. The Bluetooth 4.0 doesn't work the same and makes it lose the ability to do SMS from the car itself. Ugh.
I was hoping I could somehow put the old Bluetooth stack onto my phone to make it work properly. As of right now, Ford/Lincoln say that only Android ICS' Bluetooth stack is compatible. I feel better than the Apple community, they don't even get pictures to transfer. At least It's cool having the address book picture on my phone.
So can it be downgraded or not?
I am also interested in this (for another device though). Is it possible in principle?
No this stuff is way too complex due to the new advancement of spamsung Knox controling everything, we have very little control of our devices any more

Alternate BT that can connect to XGPS160? [Rockchip PX5 A53 | Android 9.0 | 4GB RAM]

(@Admins I think this is the correct forum to post this in, but please feel free to move it if I've chosen the wrong forum. I'm still figuring out exactly what category my device is in)
TL;DR - Trying to figure out if it's possible to get an external USB Bluetooth dongle working on my radio instead of the built-in one, so I can connect to all types of bluetooth devices, not just streaming audio
Hi all,
I'm searching for a possible solution that would allow me to connect my Android radio (AUTOPUMPKIN AA0495B, using a PX5, MCU CSN2_06252019_163051) to a Dual XGPS160 device. I installed this stereo in my track car for the purpose of running Harry's Lap Timer; currently the app is running perfectly, with a wired OBDLink EX in use for OBDII data and also connecting to a GoPro via WiFi to control the camera. The last piece of the puzzle is I want to get an XGPS160 connected for better GPS data capture (10Hz vs 1Hz of the radio's GPS). After hours spent trying to get it to pair and connect to the device, I emailed AUTOPUMPKIN support and they confirmed that this radio cannot connect to such devices, as the Bluetooth module in the radio is essentially a glorified bluetooth headset and can only connect for streaming audio (I haven't been able to determine the model number of the bluetooth module it uses). My hope is there is a USB Bluetooth dongle that I could plug into the radio and then have the radio use that instead, which would then allow it to connect to the XGPS160 (and any other type of bluetooth device).
When I go into the Car Settings on the radio, it has the following options available for bluetooth:
IVT i140
IVT i145
FC6000TN
GOC_BC5
KD6
KD6 is what is selected from the factory. Please correct me if I'm wrong, but my understanding is this list is basically the different bluetooth hardware models the radio has driver support for? If I'm correct on that, then I'm also guessing if I were to plug in a bluetooth dongle using one of the other models and change this setting, the radio would use that instead of the built-in bluetooth? I don't use the bluetooth audio streaming or phone tethering feature, so I don't care if I lose those features if it allows me to connect the radio to the XGPS160. As long as the WiFi keeps working I'm ok with it.
Sorry if I'm asking any stupid questions; I'm a programmer by background, but even after hours of reading this forum my knowledge about the hardware in these Android radio units is still very limited. That being said, I'm not opposed to modifying config files to get this working. I have Android Developer mode enabled and I can connect to the radio via ADB; I spent some time looking at the file structure and various config files so modifying those if needed shouldn't be a problem for me.
thanks!
There was another (lengthy) thread on the subject of bluetooth dongles around here somewhere. You will have to do a search for it. If I remember correctly you had to open your head unit and physically disconnect your original bt module... and even with that there was limited success in getting the thing to actually work....and of those who claimed they did get it to work also said they couldn't get anything more to connect to the dongle than what the original BT could handle
It's too bad too. I have a sound processor on my system which uses an app through BT on my phone to make adjustments and I was HOPING it would connect to the head unit. It won't
BTW... your obdlink ex usb will also work with Torque (Pro). I use it with torque and it's blazing fast and reliable.... a lot more than a BT connection!

No; it must be a specific BT type MD725 realtek device. No, you cant connect all manner of devices due to the hacked BT implementation.

Yeh I found that threat in my searches, but no one in there quite mentioned this specific scenario (Selecting one of the other options in the Bluetooth settings) so I wasn't sure. And I'm definitely not opening up the unit and cutting on the hardware; hacking config files I can do all day long, but I have no skills when it comes to soldering so I'd probably just destroy the radio in the process of trying to cut that module :laugh:
Yeh I've run the OBDLink EX with Torque as well for data logging temps on track and it worked flawlessly for that as well. BT is definitely more convenient, especially since most are running apps from their phones, but if you have a dedicated radio like these then it's a no-brainer to permanently wire up a USB device.

When you say "hacked BT implementation" I'm assuming you mean they don't use the standard Bluetooth stack built into the Android OS? That would make sense, as when I try to do anything with bluetooth from the standard Bluetooth settings menu, it doesn't do anything, doesn't see any devices available for pairing, or anything else. You can only see other devices and pair to them from the PUMPKIN Bluetooth app; the funny thing is it will go through the first steps and show the XGPS160 as being paired, but none of the apps that use the GPS actually see it as a paired device (my OBD dongle shows up, but not the GPS).
I don't understand why they didn't just use standard bluetooth that's already part of the OS, rather than use some hacky custom solution
Quick update since the last post. Spent some time tonight on google looking up the information I could find on those other bluetooth modules in the list of options on my stereo. Based on technical manuals and FCC documents, it appears the FC6000TN and BC5 are audio-only bluetooth chips that only support A2DP profile (basically the same as what I have now with the KD6); Now the IVT i140 and IVT i145 on the other hand appear to be full fledged bluetooth chips, and do support the SPP (Serial Port Protocol) that is needed by the XGPS160 (and many other bluetooth profiles) so in theory that would work. Unfortunately after searching for both of those, all I can find are ones in bare module form (i145 and i140) that would have to be soldered onto the board (assuming the pins are even compatible) and there are no USB versions of them that I could just plug in to my radio's free USB-A slot. The only thing even remotely close that comes up in Google in USB form is this adapter and I'm pretty sure it's not based on the i140 or i145.
Given that my soldering skills are non-existent, it seems I'm pretty much out of luck on getting this to work. Disappointing for sure, as I would gladly have paid more $ for the unit to come with a fully functional bluetooth module instead of this hacked audio only junk they put in it :/

Unfortunately, It wouldn't matter which BT you use from the supported BT types, BT implementation is non-standard to do stuff like act as a BT hands-free.

Yeh, that's extremely disappointing Does anyone know of any Android based radio units that have full working bluetooth? I don't mind buying a new unit for the car if I know it will work with everything.
The old intel sofia units (mtcd as well) had the bluetooth & wifi ibtegrated into the soc...and they had a standard (or at least more profiles) implemented

Bummer they don't make those units anymore :/ Then again, they may not have been powerful enough to run my track timer apps anyway.
