How to reset E220 modem via UART?

[george_santiago]

Hi Renzo

Is there a method to reset the E220 modem?
I made a code to reset the ESP32 periodically. I would like to reset the E220 modem as well. I found the.method ResponseStatus LoRa_E220::resetModule(), but it is not implemented. Is it possible to reset the E220 via the UART?

Hi George,
no not exist specified reset method.
To do something similar, I set the default configuration via the library to the device, or I use the EByte USB board and set the default config.
Bye Renzo

Hi Renzo
Thanks for the answer.

In ESP32, we have ESP.restart() method
So isn’t there an equivalent ( E220.restart() ) for the E220?
I want to implement a routine like this just in case.
Ex:
If the endpoint(ESP32) does not receive a message from the Gateway within 60 minutes, then:

E220.restart();
delay(100);
ESP.restart();

Thanks

Ahh! ok, sorry, now I understand.
I think the simplest thing to do is to flush the UART buffer, unfortunately, I put under private section the flush and cleanUARTBuffer.
But I can add this simple change in the next version.
Bye Renzo

hello best regards

I would like to know how I can link two radios, one is E32900T20D and the other is E32915T20D.

I have configured the same parameters in both radios, taking care in the direction and the channel, so that both the channel and the transmission rate match.

I have been careful to match the channel, knowing that the E32900, has a different start (862) and the E32915 at (900)

Thank you for your attention
