问题
I have a problem with sending and receiving data from elm327 device.
I tried to connect to the device using channel 01 (on Bluetooth) but it doesn't matter what command I send, I just receive the string "AT+BRSF=24\r" as an answer.
I tried also to connect at channel 16 and there I receive a string "NO DATA"
somebody knows what is the problem? thank you, Arie
回答1:
The AT+BRSF=24 response sounds like you're communicating with the wrong Bluetooth device (perhaps a headset?).
"NO DATA" sounds like an ELM327 response. What command are you sending? Try "ATZ\r" to start with.
