Hi All
I am right now working with nRf52840DK on Segger Embedded Studio (S140 SoftDevice), and I am trying to read my BLE channel map by function
sd_ble_opt_get(), but I did not get the expected result.
Basically, my code is like this:
int main(void)
{
bool erase_bonds;
// Initialize.
log_init();
timer_init();
power_management_init();
buttons_leds_init(&erase_bonds);
ble_stack_init();
gatt_init();
peer_manager_init();
db_discovery_init();
hrs_c_init();
bas_c_init();
scan_init();
ble_opt_t opt;
memset(&opt,0,sizeof(opt));
// Start execution.
NRF_LOG_INFO("Heart Rate collector example started.");
scanning_start(&erase_bonds);
// Enter main loop.
for (;;)
{
idle_state_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]);
// nrf_delay_ms(500);
}
}
The printf output from the code is:
error_code =3002, ChMap 00 00 00 00 00
If anyone knows why I got all "0" as my channel map reading output? And how could I make it right?
