I am using:
- DK52
- SDK 11
- Softdevice S132 2.0.0
I have initialized my service as follows:
#define BLE_UUID_BASE_UUID {0x05, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00}
#define BLE_UUID_BOARD_SERVICE_UUID 0x0202
ble_uuid128_t base_uuid = BLE_UUID_BASE_UUID;
ble_uuid.uuid = BLE_UUID_BOARD_SERVICE_UUID;
err_code = sd_ble_uuid_vs_add(&base_uuid, &ble_uuid.type);
if (err_code != NRF_SUCCESS)
{
return err_code;
}
err_code = sd_ble_gatts_service_add(BLE_GATTS_SRVC_TYPE_PRIMARY,
&ble_uuid,
&p_board->service_handle);
nRF Connect shows that the service has the following UUID:
00000202-0000-0000-0000-000000000005
Scanning the device from iOS using:
NSArray *services = @[[CBUUID UUIDWithString:@"00000202-0000-0000-0000-000000000005"]];
[_centralManager scanForPeripheralsWithServices:services options:nil];
The peripheral is not discovered. If I change to:
[_centralManager scanForPeripheralsWithServices:nil options:nil];
the peripheral is discovered and:
- (void)peripheral:(CBPeripheral *)peripheral didDiscoverServices:(NSError *)error {
NSLog(@"Discovered service: %@", service.UUID);
}
shows exactly: 00000202-0000-0000-0000-000000000005
I am aware of this:
I have tried to reverse the uuid but nothing changes.
Since I am using the same iOS code for other devices without any issue, I think something is wrong in my nRF52 setup.
Where am I wrong?
Tks.
