State information. Where the response values are as follows:
13 = NotOpen
14 = OpenIdle
15 = Ringing
16 = OnlineCommand
172 to 177 = waiting for connectable and/or discoverable where the lowest significant digit
equates to the value stored in S Register 512 or 555.
Note when n=16, ATI9 will return 1.
SPP connection status: 0 = not connected, 1 = connected; identical with ATI9
A2DP connection status: 0 = not connected, 1 = connected
AVRCP connection status: 0 = not connected, 1 = connected
HSP-Headset connection status: 0=not connected,1=ACL connected,2=audio connected
HSP-Gateway connection status: 0=not connected,1=ACL connected,2=audio connected
HF connection status:
SPP connection status: 0 = not connected, 1 = connected; identical with ATI9
A2DP connection status: 0 = not connected, 1 = connected
AVRCP connection status: 0 = not connected, 1 = connected
HSP-Headset connection status: 0=not connected,1=ACL connected,2=audio connected
HSP-Gateway connection status: 0=not connected,1=ACL connected,2=audio connected
HF connection status:
0 = not connected
1 = SLC connected
2 = Audio connected
3 = in call - SLC
4 = in call – audio
DUN connection status:
0=not connected
1=connected in local command mode
2=connected in remote command mode
The RSSI value in dBm. If a connection does NOT exist then a value of -32786 is returned.
A value of 0 means the RSSI is within the golden range this is quite a large band, therefore RSSI
is not always a useful indicator. Use ATI111 instead which returns the bit error rate.
Returns LinkQual which in the CSR chipset is defined as BER (bit error rate). This returns a value
which is the number of bits in error out of 1 million. Hence a value of 0 is best, and larger
values are worse. As the value approaches 1000 (BER = 0.1%) it is an indication that the link is
very bad and a large number of Bluetooth packets are being lost.
