How do I get the adress of a incoming message in fixed mode?

E220::printBoardParameters() does not display the RSSI Ambient Noise parameter properly. It shows "Disabled" regardless of the actual setting.

Changing the switch statement on line 880 to "switch (_RSSIAmbientNoise)" from "switch (_subPacketSize)" fixed the issue for me.

Hello Connor,
Im facing several errors during compilin sketch

In file included from C:\Users\admin\AppData\Local\Temp\.arduinoIDE-unsaved2023820-14888-vmu0vk.eabwm\Receive\Receive.ino:2:0:
c:\Users\admin\Documents\Arduino\libraries\E220Lib\src/E220.h:9:10: fatal error: USB/USBAPI.h: No such file or directory
 #include "USB/USBAPI.h"
          ^~~~~~~~~~~~~~
compilation terminated.

exit status 1

Compilation error: exit status 1

its reproducing only on 1.3 version of e220lib form offcial arduino repo

on 1.1.2 i have problems with pins m0, if i set it how it should be defined module.init returns

17:33:40.216 -> Error reading module config, check the wiring
17:33:40.249 -> Issue initiating the module

if i replace it mo --> aux, aux --> mo, init gone fine but i suppose that module works in wrong mode because wrong voltage levels on pins/
i got stuck(

is this only for Arduino Mega?

line 30 > there is no semicolon at the end
line 22 > //E220 radioModule(receiver, m0, m1, aux);
needs to be understood
Stream &mySerial3 = (Stream &)receiver;
E220 radioModule(&mySerial3, m0, m1, aux);

ConnorKirkpatrick a big thank you for your work

The escape character is inserted at the end in the function for sending binary data, which is used in the function for receiving binary data to interrupt reading.

Since binary data can spread across the value range of a byte, there is no wise choice for escapeCharacter.

It seems to me that it is better to leave escapeCharacter only in send and receive functions for strings and remove it from functions for binary data:

Hello, first of all thanks for your work.
I am currently trying to get communication between two E220 working and seem to be struggeling a bit. In your examples mySerial is used in the loop however it is out of scope for me.

Also as a sidenote is there any known issues working with softwareserial as i am really struggeling to get messages to send/recieve.

Thanks for your help!
