Device
Role
COMMAND
RESPONSE
AT+ROLE?
É
+ROLE:<role>
É
OK
É
AT+ROLE=<role>
É
OK
É
where <role>
0 - Slave (default)
1 - Master
2 - Slave-Loop
Slave - EGBT-045MS acts as discoverable wireless
UART device ready for transparent data ex-
change.
Master - Scans for a remote bluetooth (slave) device,
pairs, and setup connection for a transparent
data exchange detween devices
Slave-Loop - Data loop-back Rx-Tx. Used mainly for
testing.
Example: Set EGBT-045MS in master role
Bluetooth address in NA:UAP:LAP format = 0002:72:0A3C7F
From Host controller:
AT+ROLE=1

<inq3> Inquire timeout
1 to 48
48 (default)
Maximum number of devices response - EGBT-045MS
will stop inquiring once the number of devices
that responded reaches this value.
Inquire Timeout - Multiply this number by 1.28 to get the
maximum time in seconds the EGBT-045MS will
wait for a respond to an inquiry call.
Example: Set EGBT-045MS Inquire Access Mode at
Inquire access mode - 1 (rssi)
Number of devices - 3
Timeout - 10 (10*1.28 = 12.8 seconds)
Bluetooth address in NA:UAP:LAP format = 0002:72:0A3C7F
