I am able to issue AT commands in the Arduino serial monitor and also get back the necessary OKs by BT05. One of the roles it should take is iBeacon mode as per this document:
http://denethor.wlu.ca/arduino/MLT-BT05-AT-commands-TRANSLATED.pdf
But when I type in AT+ROLE3 I receive ERROR instead of OK. This holds true for anything but 0 and 1. Only those two roles will get OK as response. I am not sure what's the problem or am I missing something. I believe if other commands are working, then AT+ROLE3 should get me an OK as response. Can someone help me in here.
By the way, I am connecting MLT-BT05 to NodeMCU 8266.
