Reference Manual

the central device requests its host to enter the correct pass key (see CMD_PASSKEY_IND ).
In this case the pass key of the peripheral has to be entered on central side using the
CMD_PASSKEY_REQ command. If the entered pass key is correct, the channel will be opened
for data transmission. Otherwise, the connection will be rejected.
Example: Secured connection with security method "StaticPasskey"
1. Power-up the modules and make their UARTs accessible by the host(s) (115200 Baud,
8n1). After the power-up or after reset the following sequence is sent from the module
Info Module A Module B
⇐ Response CMD_GETSTATE_CNF : Module A
started in ACTION_IDLE mode.
02 41 02 00 01 01 41
⇐ Response CMD_GETSTATE_CNF : Module B
started in ACTION_IDLE mode.
02 41 02 00 01 01 41
2. Request the FS_BTMAC of both modules.
Info Module A Module B
⇒ Request CMD_GET_REQ with settings index 4 02 10 01 00 04 17
⇐ Response CMD_GET_CNF : FS_BTMAC of
module A is 0x55 0x00 0x00 0xDA 0x18 0x00
02 50 07 00 00 55 00
00 DA 18 00 C2
⇒ Request CMD_GET_REQ with settings index 4 02 10 01 00 04 17
⇐ Response CMD_GET_CNF : FS_BTMAC of
module B is 0x11 0x00 0x00 0xDA 0x18 0x00
02 50 07 00 00 11 00
00 DA 18 00 86
3. Configure the parameter RF_SecFlags to use "StaticPasskey" pairing method for BT
security.

to adopt the new value)
02 51 01 00 00 52
⇐ Response CMD_GETSTATE_CNF 02 41 02 00 01 01 41
4. Connect module A to module B via Bluetooth
