4.3 MODULE TO MODULE CONNECTION
The RN4870 can initiate BLE connection in Central (GAP) mode to another BLE device
supporting the UART Transparent service. The command sequence is as follows:
1. Using a terminal emulator on host PC, open a connection to RN4870 PICtail on
the enumerated COM port.
2. Type $$$ to enter Command mode
3. Type + to enable echo
4. Enter SS,C0 to enable Device Information and UART Transparent service
5. Issue command F to initiate active scan
6. Wait until inquiry finishes and finds the MAC address/address type of the device
to be connected
7. Enter C,<0,1>,<MAC address> to attempt a connection with the remote
device, where the first parameter indicates the address type that can be found in
the inquiry result: 0 for public address, 1 for private address
Once connected, characters typed in the terminal emulator are sent to the remote peer
device, and vice versa.
To kill the connection, type $$$ to return to Command mode, then type command K,1.
Figure 4-7 shows the commands and responses when connecting two RN4870
modules via UART Transparent.
