I think the sonoff smart switch solution is a gorgeous solution with many possible applications but i am actually facing network problems when using my own firmware.
I am using UDP messages to controll the device. This firmware is running without any problems on other ESP devices but on the sonoff switch about 1 out of 10 UDP messages get lost.
I could monitor the message using Wireshark network monitor but it does not appear in the arduino environment build firmware.
Since the firmware is running without problems on other devices i
expect either some electrical problem or a configuration problem. (I
already got the version with the additional capacity)
Can you maybe give some hints what to try? I already tried to contact the official support but without luck.
I got the impression that it runs more stable if the device is powered only by 3.3v (FTDI) and working worse if powered by 230V. But even with 3.3V some messages get lost.
Any idea ?
