Yes, the value of p_ble_evt->evt.gap_evt.conn_handle is (0000). Do I miss some parameters or settings for the API function? Could you please show me an example to use the API function? Thanks

Is that (0000) the value of p_ble_evt->evt.gap_evt.conn_handle; as well?

I add some debug message as below

ble_opt_t opt;
  	memset(&opt, 0, sizeof(opt));
	printf("p_gap_evt->conn_handle =%04X\n",p_gap_evt->conn_handle);
  	opt.gap_opt.ch_map.conn_handle = p_gap_evt->conn_handle;
	printf("opt.gap_opt.ch_map.conn_handle =%04X\n",opt.gap_opt.ch_map.conn_handle);
  	uint32_t error_code = sd_ble_opt_get(BLE_GAP_OPT_CH_MAP, &opt);
  	printf("error_code =%x, ChMap %02X %02X %02X %02X %02X\r\n",error_code,
    		opt.gap_opt.ch_map.ch_map[0], opt.gap_opt.ch_map.ch_map[1],
                     opt.gap_opt.ch_map.ch_map[2],
    		opt.gap_opt.ch_map.ch_map[3], opt.gap_opt.ch_map.ch_map[4]);

The result as below

p_gap_evt->conn_handle =0000

opt.gap_opt.ch_map.conn_handle =0000

Error: File: (null), Line: 0, Error code: 7

error_code =3002, ChMap 00 00 00 00 00

Yes, I saw that from your code snippet. I just wanted to know if you checked what the actual value is when passing it to sd_ble_opt_get . You should only get the BLE_ERROR_INVALID_CONN_HANDLE if this handle is incorrect.

I pass "p_ble_evt->evt.gap_evt.conn_handle" that come from the application's BLE Stack events to opt.gap_opt.ch_map.conn_handle .

What is the value of opt.gap_opt.ch_map.conn_handle that you pass to sd_ble_opt_get?
