Seeking expert on LoRa module found on Arduino MKR1310 to commission library modifications.

[RiccardoPelizzari]

As per the title I am looking for an expert on the LoRa module present on the Arduino MKR1310 in order to commission modifications on the LoRa library and/or firmware present on board the module.
I am using the MKR1310 in several projects but I am experiencing a number of problems using this library, so I need to make the library as functional as possible for my purposes.
The problems I am experiencing are as follows:

• using the receive with callback seems to work, but after a while it works it stops receiving(random event), I also did some checks on the DIO0 pin with a logic analyzer and it seems that it no longer sends the receive signal, if I reset the arduino everything goes back to working.
• I cannot use the cad function to check if the band is clear before sending a packet, I need to be able to use it.
• sometimes (random event) even if i send one packet the other device receives 2 packets, i don't know if it is due to sending 2 packets or if the receiver doesn't reset the IRQ.
  best regards
