Code: Untitled.cpp Select all

class MyAdvertisedDeviceCallbacks : public BLEAdvertisedDeviceCallbacks

{

	void onResult(BLEAdvertisedDevice advertisedDevice)

	{

		printf("Name %s, Address %s, RSSI %d\n", advertisedDevice.getName().c_str(), advertisedDevice.getAddress().toString().c_str(), advertisedDevice.getRSSI());

		//data = json.createNestedArray("dat");

	}

};

advertisedDevice.getName().c_str() returns an empty string after the first time a iBeacon is received. The beacon does have a name and my phone test app receives the name without any problems. advertisedDevice.toString().c_str() also omits the name. All other info is returned correctly

I suspect that I am facing the same problem. I am using SampleAsyncScan.cpp by nkolban, and the scan only returns BLE module information in the first scan, and not subsequent ones.
