Hi. I'm trying connect (using Termite terminal) HC-05 BT module with ELM327. HC-05 module is connected with PC by CH340 converter. It's version ZS-040, so I connected EN pin to 3.3V and now I configure module:
AT+RESET OK AT+ORGL OK AT+ROLE=1 OK AT+CMODE=0 OK AT+NAME=HC05 OK AT+INIT OK AT+PAIR=1d,a5,68988b,20 OK AT+BIND=1d,a5,68988b OK AT+LINK=1d,a5,68988b FAIL
Link step failed, when I power off module, switch EN pin to GND and now power on, green LED of ELM327 blink once on every 3-4sec, HC-05 trying connect with ELM327 but unsuccesfully
Any ideas? I'm doing something wrong or it's look like broken BT module?
PS. I haven't possibility to connect HC-05 as master with PC or phone. AT+LINK every time failed.
