‣ 4: ESP_IO_CAP_KBDISP /*!< Keyboard display */
<key_size>: encryption key size, range : [7, 16]
<init_key>:
‣ if bit0 is 1, it means ESP_BLE_ENC_KEY_MASK // exchange the encryption key
‣ if bit1 is 1, it means ESP_BLE_ID_KEY_MASK // exchange the IRK key
‣ if bit2 is 1, it means ESP_BLE_CSR_KEY_MASK // exchange the CSRK key
‣ if bit3 is 1, it means ESP_BLE_LINK_KEY_MASK // exchange the link key(this key
is used only in the BLE & BR/EDR-coexist mode)
<rsp_key>: response key
‣ if bit0 is 1, it means ESP_BLE_ENC_KEY_MASK // exchange the encryption key
‣ if bit1 is 1, it means ESP_BLE_ID_KEY_MASK // exchange the IRK key
‣ if bit2 is 1, it means ESP_BLE_CSR_KEY_MASK // exchange the CSRK key
‣ if bit3 is 1, it meansESP_BLE_LINK_KEY_MASK // exchange the link key(this key
is used only in the BLE & BR/EDR-coexist mode)
This configuration should be set before the BLE connection is established.

Set Command:
AT+BLEENC=<conn_index>,<sec_act>
Function: to start a pairing request.
OK
<conn_index>: index of BLE connection; only 0 is supported for the single connection right
now, but multiple BLE connections will be supported in the future.
