The product name/variant.
The CSR firmware build number.
The AT firmware build number. For internal use only.
The AT firmware revision.
A 12 digit hexadecimal number corresponding to the Bluetooth address of the BTM device.
The manufacturer of this device.
The maximum size of trusted device database.
The manufacturer of the Bluetooth chipset.
The chipset format.
SPP connection status:
0=not connected
1=connected in local command mode
2=connected in remote command mode
The reason why a “NO CARRIER” resulted in the most recent attempt at making an outgoing
connection. Where the response values are as follows:
0 = No prior connection
1 = Connection timeout
2 = Connection attempt cancelled
3 = Normal disconnection
4 = Peer device has refused connection
5 = Service profile <uuid> requested not available on remote device
6 = Connection has failed
32 = ATH was entered
33 = Incoming connection aborted because too many rings
34 = Unexpected incoming connection
35 = Invalid address
36 = DSR is not asserted
37 = Call limit of 65531 connections has been reached
38 = Pairing in progress
39 = No link key
40 = Invalid link key
255 = Unknown Reason
The last ERROR response number.
The Sniff status is returned as follows:-
Response: <cr,lf>a:b,c,d,e<cr,lf>OK<cr,lf>
Where ‘a’ = 0 when not online and 1 when online and Sniff has been enabled, ‘b’ is the Sniff
Attempt parameter, ‘c’ is the Sniff timeout parameter, ‘d’ is the minimum sniff interval and ‘e’
is the maximum sniff interval. All parameters ‘b’, ’c’, ’d’ and ‘e’ are given as Bluetooth slots
which are 625 microseconds long converted from values of S Registers 561, 562, 563 and 564
respectively.
The current boot mode
The maximum length of an AT command, not including the terminating carriage return
Codec Output Maximum Gain Range
Codec Input Maximum Gain Range
Bluetooth version
Audio connection status: 0 = off, 1= on
Returns the number of bytes pending to be sent in the rf buffer when a connection is up.
Version number of Multipoint application (Note: ATI is provided for compatibility in multipoint
mode, other AT commands are not available).
