Hey there, I just got a set of two E220-900T22D modules, but I’ve spent the past week trying to get them to work. I’ve tested them with a Pi Pico, an Arduino, an ESP8266, and a Wemos ESP8266.
All the tests I did were using get_config, set_config, and sendFixedTransmission.
And yes — before you say it — I uncommented the lines at the top of the file for the correct board and adjusted the GPIO setup accordingly. I am on a 5V power supply for the module and have pullups 4.7khoms.
Here’s what happens:
With the Pi Pico, I get error 12 (check connections). I’ve tested other UART devices on the same IO pins, and they work fine.
With the Arduino, same thing — error 12.
On the ESP8266, sometimes it says success, but if I run it again, I’ll get error 7 (data not matching), and other times error 11.
What is going on??
Is the library code wrong? I’ve seen lots of people with the same problem, but no one seems to find a solid answer — it looks like everyone just abandons the issue…
Thanks in advance if anyone actually reads this and can give me a clue about what’s happening.
