send a value to the bt-Device

Hi,
i am using your example for a Radon sensor (Radoneye). So far i can read the last value from the sensor with this. But my sensor needs to write a value to a characteristic in order to send a produce an updated value. Any idea how i could manage this with BLETracker?

The code would be:

BLERemoteCharacteristic* p2RemoteCharacteristic;
...
p2RemoteCharacteristic = pRemoteService->getCharacteristic(char24UUID);
if(p2RemoteCharacteristic->canWrite()) {
p2RemoteCharacteristic->writeValue(0x50);

After this a new sensor value is send on a second characteristic.

Thaks for your help,

Michi
