OBD Bluetooth not working - DaveRack - 10-11-2022 Hello, I have problems establishing a bluetooth obd connection with OAP. Manually connect and pair works, the adapter also flashes short blue when the OAP dashboard is started, but that's it. Bluetooth Dongle TP-Link UB400 (CSR8510 A10 chipset). OAP logfile with errors attached. RE: OBD Bluetooth not working - Daniel_BlueWave - 10-11-2022 Did you pair your adapter with Rpi? What OBD adapter are you using? Did you follow configuration from here: https://bluewavestudio.io/community/thread-1865.html ? RE: OBD Bluetooth not working - DaveRack - 10-11-2022 Yes, paired it with Rpi. Pair and connect with bluetoothctl works. yes: ObdProbePeriod=5 ObdDeviceType=2 ObdAdapterRfCommAddress=XXXX ObdAdapterRfCommChannel=1 (I tested channel 1 and 2 because sdptool records shows channel 2 for my ELM327.) ObdMaxNoDataResponseCount=20 It is an elm327 aliexpress adapter, but works with Windows and Android(AT commands also work). RE: OBD Bluetooth not working - BlueWave - 10-11-2022 Looks like your ELM327 is not genuine one. It probably does not support some commands from startup sequence https://www.bluewavestudio.io/community/showthread.php?tid=2042&pid=11931#pid11931. RE: OBD Bluetooth not working - DaveRack - 10-11-2022 I tested the at commands manually in windows. See the screenshot. Are the results correct? RE: OBD Bluetooth not working - DaveRack - 10-14-2022 The cheap ELM adapter was to blame. With a Vgate iCar Pro it works immediately.. RE: OBD Bluetooth not working - Daniel_BlueWave - 10-15-2022 Cheap not always mean good enough Thanks for the feedback. Enjoy. |
