v. Also, Module response depends on ENBGAP settings. Refer section
1.2 “Enable GAP Central role” for more details.
vi. Actual values of PIN, MITM, IOTYPE are displayed as per the
current settings of device.
vii. Response to the settings command varies as per the device, e.g.
for LM068/LM074 modules it includes MODEM command.
4.3 UART Settings commands:
4.3.1 “AT*BAUD”\r\n
i. Query and set command
ii. Baud rate query: “AT*BAUD=?”\r\n
iii. Baud rate query report: “REP*:BAUD=19200(2)”. Number in curly
brackets shows the serial number as per below table.
iv. Baud rate set command: “AT*BAUD=3” (Set Module baud rate as
38400 bps)
v. Module need to not to perform power-on-off after change of baud
rate setting.
