Hi,
I use an nRF51822 QFAC A1 and my goal is to disable BLE in a powerdown mode, then when I press the pushbutton I want to restart BLE. Tried using BLEDevice::shutdown() function but when I restart BLE with BLEDevice::init(), the device can be scanned from the central but I am not able to see any service.
Here is the portion of code with the defined function :
BLEDevice ble;
void BLE_Init()
{
ble.init();
ble.onConnection(BLE_OnConnectionCb);
ble.onDisconnection(BLE_OnDisconnectionCb);
//DeviceInformationService deviceInfo(ble, "WBT", "Model1", "SN1", "hw-rev1", "fw-rev1", "soft-rev1");
ble.accumulateAdvertisingPayload(GapAdvertisingData::BREDR_NOT_SUPPORTED | GapAdvertisingData::LE_GENERAL_DISCOVERABLE);
ble.accumulateAdvertisingPayload(GapAdvertisingData::COMPLETE_LIST_16BIT_SERVICE_IDS, (uint8_t*)BLE_UUID_LIST, sizeof(BLE_UUID_LIST));
ble.accumulateAdvertisingPayload(GapAdvertisingData::GENERIC_HEART_RATE_SENSOR);
ble.accumulateAdvertisingPayload(GapAdvertisingData::COMPLETE_LOCAL_NAME, (uint8_t*)BLE_FRIENDLY_NAME, sizeof(BLE_FRIENDLY_NAME));
ble.setAdvertisingType(GapAdvertisingParams::ADV_CONNECTABLE_UNDIRECTED);
ble.setAdvertisingInterval(Gap::MSEC_TO_ADVERTISEMENT_DURATION_UNITS(1000));
ble.startAdvertising();
SensorService_Init(&ble);
}
void BLE_Shutdown()
{
ble.shutdown();
}
Then in the main file we have this in the button interrupt callback :
switch(state)
{
case 0 :
BLE_Shutdown();
state = 0xFF;
break;
case 0xFF :
BLE_Init();
state = 0;
break;
}
And finally in the main loop we have this :
switch(state){
case 0: //Wait for Event state
//Wait for measurement callback or sending buffer through BLE
next_state = 0;
BLE_WaitForEvent();
break;
case 0xFF : //Power down state
deepsleep();
break;
}
Could you tell me what is the origin of the problem and how to solve it ?
PS : I use mbed with SoftDevice S110 7.3.0
Best regards,
Guillaume
