BC832 module is available with firmware supporting AT commands. Part number is BC832-AT.
Brief description of AT commands
 Each command line consists of a prefix, a body and a terminator.
 All command lines begin with the prefix AT (ASCII 065, 084) or at (ASCII 097, 116).
 The body is a string of characters in the ASCII range 032-255. Control characters other than
<CR>(carriage return; ASCII 013) and <BS> (back space; ASCII 008) in a command line are ignored.
 The terminator is <CR>.
 There is no distinction between upper-case and lower-case characters. A command line can have a
maximum length of 80 characters. It is automatically discarded if the input is longer. Corrections are
made
 AT command is case-insensitive, following /r/n for end code.
 The default baud rate is 9600 one stop bit and no parity
Command mode
When P0.02 of nRF52832 (pin 13 of BC832) is pulled high, it is set to AT command mode. In AT command
