Just thought I'd provide an update on this. I now have it receiving and transmitting really reliably using MQTT instead of ser2net. I migrated away from ESPEasy to an alternative o/s but it should still work if set up correctly.

It doesn't appear to. I may have to capture the raw output from the ESP.

I may also try putting the TX in via the USB port by cutting up a USB cable.

I am experiencing the same issue with my ESP01 to RFLINK connection. RX is OK. TX commands (i.e 10;PING;) can be seen in ESP01 log but do not seem to get transmitted to the Arduino / RFLINK board. The RFLINK board will TX happily when connected via USB however. Has anyone come across a solution to t...

I have exactly the same experience with these UNI-COM devices. Bought at Costco in UK
