5.2.2 Get Connection Status or Query Current Connection Status

Table 5-3. Format
Firmware Version 1.0	Firmware Version 1.2 and Later
`GK`	`QCCS`
Note: All firmware version 1.0 syntax remains valid in version 1.2 and later.

To obtain the current connection status of the RNBD350 module, use the “Get Connection Status ” or “Query Current Connection Status” command, GK or QCCS.

This command does not require any input parameters. Depending on the module's current connection status, the command provides different outputs:

If the RNBD350 module is not currently connected to any device and the user uses the command without the optional parameter, the output will be “none”.
If the RNBD350 module is connected to a device, the “GK or QCCS” command returns the following connection information:
1. <Peer BT Address>,<Address Type>,<Connection Type>, where
  - <Peer BT Address> – Is the 6-byte hex address of the peer device
  - <Address Type> – Is either 0 for public address or 1 for random address
  - <Connection Type> – Specifies if the connection enables the UART transparent feature, where 1 indicates UART transparent is enabled and 0 indicates UART transparent is disabled
