Hello,
I have modified my device name (nRF52, BLE) per the function below. When flashed to a board, I then use nRF connect to look for this device.
Using Windows nRFConnect and the nRF52 dongle, the name is "JK_BXY". Using iPhone and nRFConnect, the name is "JUNK_BL". These are scanning the same device at the same time!
I have just started to try and understand how this could be, but it seems that the iOS BLE communication must do something different such that the gap_params_init isn't called or is later overridden. But i cannot find another function that does this (overrides).
The only apparent place sd_ble_gap_device_name_set(...) is called is in this function, which clearly only calls out the modified name.
Does anyone have any suggestions on where to look?
static uint32_t gap_params_init(void)
{
uint32_t err_code;
ble_gap_conn_params_t gap_conn_params = {0};
ble_gap_conn_sec_mode_t sec_mode;
BLE_GAP_CONN_SEC_MODE_SET_OPEN(&sec_mode);
err_code = gap_address_change();
VERIFY_SUCCESS(err_code);
#if (1)
/* Change name from JUNK_BL which is the define DEVICE_NAME */
uint8_t devname[6] = {'J','K','_','B','X','Y'};
err_code = sd_ble_gap_device_name_set(&sec_mode,
(const uint8_t *)devname,
7);
#else
err_code = sd_ble_gap_device_name_set(&sec_mode,
(const uint8_t *)DEVICE_NAME,
strlen(DEVICE_NAME));
#endif
VERIFY_SUCCESS(err_code);
gap_conn_params.min_conn_interval = MIN_CONN_INTERVAL;
gap_conn_params.max_conn_interval = MAX_CONN_INTERVAL;
gap_conn_params.slave_latency = SLAVE_LATENCY;
gap_conn_params.conn_sup_timeout = CONN_SUP_TIMEOUT;
err_code = sd_ble_gap_ppcp_set(&gap_conn_params);
return err_code;
}
