1 - hci_enc_mode_pt_to_pt

 

2 - hci_enc_mode_pt_to_pt_and_bcast

23. Delete Authenticated Device from List

COMMAND

RESPONSE

AT+RMSAD=<addr>

É

OK

É

where  <addr> = 48 bit bluetooth address 
 

 

   in NAP,UAP,LAP format

Example: Remove from Authenticated Device list a Blue-
tooth device having address = 00:02:72:0A:3C:7F

Bluetooth address in NA,UAP,LAP format = 0002,72,0A3C7F

From Host controller:

 

AT+RMASD=0002,72,0A3C7F

É

EGBT-045MS response if deletion is successful

 

OK

É

EGBT-045MS response if remote device address is not in the list

 

ERROR(15)

É

Caution:  

Entering
 

AT+RMASD

É

will delete ALL authenticated device from the list!

24. Find Device from Authenticated Device List

COMMAND

RESPONSE

AT+FSAD=<addr>

É

OK

É

where  <addr> = 48 bit bluetooth address 
 

 

   in NAP,UAP,LAP format

Note: AT+FSAD returns a FAIL response if device is not 
in the authenticated list

25. Query Total Number of Device from Authenti-
cated Device List

COMMAND

RESPONSE

AT+ADCN?

É

+ADCN:<total>

É

OK

É

where 
<total> = total number of devices in the authenticated 
device list

26. Query Most Recently Used Authenticated De-
vice

COMMAND

RESPONSE

AT+MRAD?

É

+MRAD:<addr>

É

OK

É

where  <addr> = 48 bit bluetooth address 
 

 

   in NAP:UAP:LAP format

27. Query Current Status of the Device

COMMAND

RESPONSE

AT+STATE?

É

+STATE:<stat>

É

OK

É

where 
<stat> = Current Status, any one of the following:

 

INITIALIZED

 

READY

 

PAIRABLE

 

PAIRED

 

INQUIRING

 

CONNECTING

 

CONNECTED

 

DISCONNECTED

 

UNKNOWN

28. Initialize SPP Profile

COMMAND

RESPONSE

AT+INIT

É

OK

É

 / FAIL

É

29. Query Nearby Discoverable Devices

COMMAND

RESPONSE

AT+INQ

É

+INQ: <addr>,<class>,>rssi>

É

OK

É

where  <addr> = 48 bit bluetooth address 
 

 

   in NAP:UAP:LAP format

 

<class> = Device Class

 

<rssi> = RSSI

This command will scan and report all nearby dicov-
erable Bluetooth devices. The same device may be 
reported more than once.

This command will work only if EGBT-045MS is set to 
work as a master device, i.e. AT+ROLE=1, and after 
AT+INIT is executed.

Example: Discover nearby devices
