@Dominik-Paľo Hm, it seems that there is problem in Windows 10 TP > http://answers.microsoft.com/en-us/insider/forum/insider_wintp-insider_devices/windows-10-serial-usb-problems/438de66f-7294-4c06-b4fb-89b45d005ca0?tab=question&status=AllReplies&status=AllReplies%2CAllReplies

Hi,

I'm trying to upload MyMQTT Broker to Arduino Uno and all my attempts fails with error:

avrdude: verification error, first mismatch at byte 0x3a8a
0xdf != 0x14
avrdude: verification error; content mismatch

I tested it with 2 different Arduino Uno boards and 2 different Arduino Mega boards and there is same error on all (addresses are different on Mega boards)

I'm use latest version of libraries and sketches (from github), but with small changes - I'm using Wiznet W5100 ethernet shield, so I uncommented SOFTSPI in RF24_config.h and added include for DigitalIO.h into MQQTTGateway sketch. I have same problem with SerialGateway, EtheretGateway and probably other examples from MySensor directory...

Other examples/skecthes works fine (e.g blink example, my custom sketches from older projects...) => Arduino boards are OK.

OS: Microsft Windows 10 Technical Preview
Arduino IDE: 1.0.6 (I tested it also with 1.5.8 beta)
