AT command reference

AT commands are used to configure the module and trigger operations. AT commands are

transmitted over the UART channel from the external MCU to the Bluetooth module. AT

commands have the following syntax:

AT + CMD = parameter0, parameter1, …\0x0D\0x0A

AT + CMD\0x0D\0x0A

Each line must be always terminated by the 0x0D 0x0A characters and only a single

command per line is allowed.

The response to an AT command can be OK if the command was successfully executed, or

ERROR if an error occurred and has the following syntax:

\0x0D\0x0AOK\0x0D\0x0A

\0x0D\0x0AERROR\0x0D\0x0A

Some AT commands can generate events. Events are always reported as follows:

\0x0D\0x0A+EVENT: parameter0, …\0x0D\0x0A

Each event is always bounded by the characters 0x0D 0x0A and can have zero or more

parameters. The command syntax is case insensitive.
