I would like to use the EBYTE E104-BT52 module on my device and connect to it via an Android smartphone.
But what if the client device is running BLE 4.2 and it will be unsecure pairing.
To avoid this I would use passkey which will be showed on the device’s display.
But I dont find AT+PASSKEY ( or something similar ) in the user manuals:
E104-BT07, E104-BT08, E104-BT5032A/B, E104-BT52, E104-52X, E104-BT09, E104-BT5040U(ble 4.2), E104-BT5032A/B.
( AT+PASSKEY is in the E104-BT40 user manual ( dual-mode bluetooth module ble 4.2 spp 3.0 Classic ) ).
