E32-TTL-100 Frequency/Channel Configuration

Hi guys! I am currently trying to use an E32-TTL-100 LoRa Transciever Module and I can't figure out how to set up the frequency and channel (I need it to be exactly 343.7MHz) through an Arduino UNO. I've gone through the datasheet and I still don't understand exactly what I have to do.

Also, in what "language" do I have to send the parameters to the Transciever Module (hexadecimal, ASCII, idk).

This is very urgent and if someone can help me, please do! Every bit of help is welcomed.

Sorry for the slow reply, the forum is supported by volunteers who can be busy on other stuff.

You have not said which of the frequency band E32 modules you are using ?

433MHz by default Also I said i need it on 343.7, I meant 433.7

The manual implies that you cannot set the frequency to 433.7Mhz (or 343.7);

4 CHAN Communication frequency( 410M + CHAN * 1M) Default 17H( 433MHz)

So you can set it to 410,411,412 etc

Thank you !!!
