BC127 AT Command


I am using BC127 with firmware Melody Audio V5.0 RC11 .Can anyone help me out how to enable AT command in bc127 .



Unsure what you mean by “enable AT command”.

You need to use a terminal program to communicate with BC127, once the connection is properly setup (correct port number and baud rate) you can send AT commands to BC127. Please refer to Melody Audio User Guide Section 2 for details, the doc is available on Source (https://source.sierrawireless.com/resources/airprime/hardware_specs_user_guides/bc127-melody-audio-6-user-guide/).
