BLE pairing with "numeric comparison".

[Duracell]

Hi All

I tried to use the numeric compairison BLE (4.2) pairing mechanism in the example "gatt_security_server".
For this, I set:

Code: Select all

esp_ble_io_cap_t iocap = ESP_IO_CAP_KBDISP;

This shows a passkey on the Terminal and triggers a POP up on the app, where I can confirm, that the passkey on the app is the same as in the esp32 terminal.
When I confirm, nothing happens - the peripheral just times out.
I tried with different "clients".

Anybody got this to work? (The passkey method - ESP_IO_CAP_OUT - works perfectly).

Many thanks
Dura
