These are the errors i am having while importing P2PMQTT.h in my arduino code

Hi Andreas, I'm doing a lot of test to understand the origin of the communication issue. I saw your suggestion to shift to [2] the payload start. Anyway i's not sufficient. Numbers shown of the App changes with the potmeter rotation but with no sense. I added some Serial.print in the P2PMQTT.cpp to check what was passed to the USB driver, just after the topic name "us", rotating the potmeter I have the strange ascii characters, but not related to the value red by the analog input. Changing the type of val from int to byte to char, what I read change but I don't manage to see on the serial something understandable VS analog read value. Furthermore, the issue I told you (the stuck at value 120 read by the analog port) is still there. I think the problem is on the Arduino code side. On the Android side we should go back to [0] as payload start, as the classes and method seem to be ok. Do you have an idea?
tnx, Andrea.
