E32-TTL-100 me ajudem!!!

Hello friends, I'm new forum
I need help getting my E32-TTL-100 to work, but I'm getting it. Have any of you ever worked with this module?
Could anyone give me some example of Arduino code?

I have been trying and searching the internet for many days and I can not make it work, please help me.
thank you.

Do you have the password (what damned stupid company does deliver datasheets encrypted?) for the manual they offer for download?

I looked at the manual, but I did not succeed.
I'm trying, but so far nothing.

Post a link to a unencrypted version of the manual.

That one is encrypted. I told you we need a link to the unencrypted version of the manual!

I'm trying to do this.

I was able to unblock the pdf

It seems that this module is transparently transmitting serial data in the LORA band. So set pins 1 and 2 according to your needs (you didn't tell us yet), connect pin3 to Arduino TX, pin4 to Arduino RX and pin 5 to and free digital input on the Arduino. Pin6 is connected to 5V and pin7 to GND.

I am using arduino sample source code (eHead_client.pde from RadioHead library) the error is occurring in this part below:
if (! driver.init ())
Serial.println ("init failed");

I'm using links according to the library:
Arduino <-----> module e32 - ttl100
/// GND ---------- GND (ground in)
/// 5V ----------- VCC (5V in)
/// D4 pin ----------- M0 (pin control input mode for radio)
/// pin D5 ----------- M1 (pin control input mode for radio)
/// D6 pin ----------- RXD (serial data input from Arduino to radio)
/// pin D7 ----------- TXD (serial data output from the radio to Arduino)
/// pin D8 ----------- AUX (output of auxiliary pin from radio to Arduino)

Friend, have you worked with this module yet?

solved the problem.
the cause of the problem is that my mega arduino was connected to the usb port of my pc, then I removed the usb cable and it worked perfectly.
thank you everyone for the attention
