BLE: about the connection parameter setting.

Postby zhuzhu0902102 » Tue Dec 26, 2017 8:48 am

There are some questions about connection parameter setting, while I use the demo of gatt_client and gatt_server.

Question 1: May I modify the CONNECT_REQ parameters in the application on ESP32 as a client, and how to change it?

The CONNECT_REQ paramter :
Connection Interval (ms): max and min Interval
Latency:
Timeout:

Question 2: Whether there is no need to set the connection parameters in the application on ESP32 as a server? I only find a function of esp_ble_gap_update_conn_params() is be used, and that is not properly of the using in the demo of gatt_server.

Question 3: I want to know how to use esp_err_t esp_ble_gap_set_prefer_conn_params(esp_bd_addr_t bd_addr,
uint16_t min_conn_int, uint16_t max_conn_int,
uint16_t slave_latency, uint16_t supervision_tout);
when I put this function before the esp_ble_gattc_open() in the demo of gatt_client, but the client can't normally connect to server.

Is there anyone could help me and give me the answer about the above questions, thank very much.
