I'm using a Teensy 3.1 and BlueSmirf Serial Module RN-42 (silver) to transfer data via serial.
The issue I am having with one of those modules is that it detects as a bluetooth keyboard (FireFly-9ED5). It also doesn't ask me to enter 1234 pin to establish connection, and I am not getting serial com port out. Another module detects correctly as serial device with 1234 pin (connects as RN42-XXXX).
Did anyone face a similar issue before? Do I need to reset that BlueSmirf RN-41 to make it detect as serial device?
