Hi all

I have this strange problem:

IDF: v3

Example Code: examples/bluetooth/gatt_security_server

If I change the code to use passkey pairing with MITM:


esp_ble_auth_req_t auth_req = ESP_LE_AUTH_REQ_SC_MITM_BOND;
esp_ble_io_cap_t iocap = ESP_IO_CAP_OUT;


Everything works as expected. After ...

This works now with the latest version from master.

There are new functions in bt.h:

Hi

Did you have success with the ESP_IO_CAP_KBDISP numeric comparison method for pairing?

Thanks

Hi All

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

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 ...

I could not find any API to do this.

Anybody knows how to do this?

I already tried changing BTM_BLE_ADV_TX_POWER in ...
