Pair OBD2 on Android car stereo
#21
I'm using Torque Pro from the Android play store. Adapter is an OBDLink MX connected through Bluetooth. Works like a charm, but my radio is 4.4.4. Maybe there's an issue with 5.1? I guess I'll find out soon enough because I just bought a 5.1 unit for my other car as well as another OBDLink MX

<Meta: Will start new thread if this is deemed too old to continue.>

Most of my previous posts (Music player, Google Play Music) were from setting up my unit on my benchtop while waiting shipment of the correct harness for installation. I have finally gotten around to getting the unit in my car and now finding Bluetooth/OBDII/Torque problems that match what others are seeing in this thread.

Since installation I've been having issues with the Bluetooth being extremely flaky on my JY-UL135, running the latest 5.1.1 rom (20 Sept 2016 JY-1.90) and using the provided Torque.apk installed from ApkInstaller. I've tried the steps outlined in post #11 of this thread with the exception of factory reset which I'm holding out on as a last resort. I have also tried clearing data and cache from the Torque app between deleting BT profiles.

Main issue is that Torque cannot see the OBDII adapter (bought from Joying) most of the time. If I delete and re-create the pairing and restart the unit, it *may* see it and work. It might even work after a reboot, but the next time I go to use the car it won't see it anymore. OBD logo with blue surround is still present in the main status bar, but no Bluetooth logo. In this state the "phone" logo of the Torque status icons (the four blue ones in the upper left of Torque main page) is blacked out and Torque says I have no Bluetooth enabled. Would love to know how to fix this.

Secondary issue is that pairing of my phone is also hit and miss. Sometimes it fails to pair on startup, other times it pairs but lacks media connectivity. Delete and recreate and it usually succeeds, but then reverts as above.

On the off-chance that range is a factor (OBDII port is about 1m away from unit on other side of steering column. Doubtful, but possible) I have ordered an OBDII extension cable to try get it closer. Anyone else tried this?

Anyone tried USD OBDII devices, instead of BT OBDII?
If compatible, it would be preferable to avoid BT problems and because an usb device turns on and off automatically along with HU instead of BT manually (or, maybe, always turned on draining car battery).

Was wondering that myself. I see Torque does have the option for USB OBD but not sure if the head unit's USB would work with it. I'm thinking I'll give it a shot if I don't come right after a factory reset. Might try this one:

...or maybe a cheaper one like this: https://it.aliexpress.com/item/ELM327-US...3ac9aa0b6b
just to try if usb link to Torque can work.

Good idea, I ordered this one: https://www.aliexpress.com/item/Super-mi...26475.html to test out. If it works, great. If not it's <$10 wasted. Either way I'll feed back to this forum on the outcome. Another rationale for trying USB OBD is a concern I have for overloading the BT on this unit, if I'm doing A2DP audio and still have a constant OBD data stream. Probably unfounded though as BT 2.1 is rated for nominal data speeds of 2.1Mbps and the OBD data stream is only ~10.5Kbps.

In the meanwhile I *might* have had some success this side of a factory reset. I went back to the Torque OBD settings and re-enabled both the check marks for turning BT on/off with Torque and the "only if BT was off" options. I had deselected those because, well BT can't be switched on/off in this firmware so I figured it was irrelevant and may only cause problems. Either way it seems to work okay-ish for now, that is for the past two trips it has auto-started Torque and connected to the OBD, however each time there were intermittent drop-outs of connectivity between Torque and the OBD. Making progress though.

Hi Guys

I received an email from Joying today. Link to new software..... completely fixed my pairing problem with my ELM OBD2 device.

Reporting back on the outcome of USB OBDII and Torque: http://imgur.com/gallery/XkU4Ajf

I set Torque to USB connection, plug in the device and get a popup requesting permission for Torque to access the USB. Permission granted but Torque does not see the device. Tried both USB ports naturally.

Back to Bluetooth we go

pwood - Which software was it?

I'm very sorry to hear this...
Have you also tried a powered USB Hub?
