I am unable to change device configuration for e34-2G4D20D

Hello xreef, I trust you are doing well.

First of all, I want to express my appreciation to you for creating such a concise and working library. I took a leap of faith and tried using it for e34-2G4D20D and ESP32, giving no regard to library compatibly and it worked well after a few tweak. so at the moment, I want to reconfigure my e34-2G4D20D and increase the air data rate and UART_BPS_RATE but the message I get on my serial monitor keeps saying "-----:No response from device! (Check wiring)". But I am able to send and receive with both transceivers.

I also observed that the parameters I set to e34-2G4D20D using Configuration object is not applied when I print configuration.

I am using e34-2G4D20D on ESP32

below is my code:

/*
 * EBYTE LoRa E32
 * send a transparent message, you must check that the transmitter and receiver have the same
 * CHANNEL ADDL and ADDH
 *
 *
 * https://mischianti.org
 *
 * E32        ----- esp32
 * M0         ----- 19 (or GND)
 * M1         ----- 21 (or GND)
 * RX         ----- TX2 (PullUP)
 * TX         ----- RX2 (PullUP)
 * AUX        ----- 15  (PullUP)
 * VCC        ----- 3.3v/5v
 * GND        ----- GND
 *

As can be be observed in the codes above, I tried to fetch configuration from e34-2G4D20D module after setting it programmatically it returned configuration parameters different from the ones I set. Please see output below:

17:58:48.311 -> SpeedUARTDatte : 100 -> 19200bps
17:58:48.311 -> SpeedAirDataRate : 101 -> 19.2kbps
17:58:48.311 -> OptionTrans : 1 -> Fixed transmission (first three bytes can be used as high/low address and channel)
17:58:48.311 -> OptionPullup : 0 -> TXD, RXD, AUX are open-collectors
17:58:48.311 -> OptionWakeup : 100 -> 1250ms
17:58:48.311 -> OptionFEC : 1 -> Turn on Forward Error Correction Switch (Default)
17:58:48.344 -> OptionPower : 1 -> 17dBm
17:58:48.344 -> ============================-----===================================
17:58:48.344 -> -----:No response from device! (Check wiring)

17:58:49.874 -> OptionTrans : 0 -> Transparent transmission (default)
17:58:49.874 -> OptionPullup : 1 -> TXD, RXD, AUX are push-pulls/pull-ups
17:58:49.874 -> OptionWakeup : 110 -> 1750ms
17:58:49.874 -> OptionFEC : 0 -> Turn off Forward Error Correction Switch
17:58:49.919 -> OptionPower : 11 -> 10dBm
17:58:49.919 -> ============================-----===================================

Please advice on how to resolve this issue.

My goal is to further increase the speed of transmission and size of byte. Thanks
