I have a problem with connecting my arduino nano to the hoperf RFM95W.
I have two nanos connected each to one rfm95w as per image.
I uploaded to them the default lora Sender and lora receiver from sandeep
it did work perfectly when connected to the arduino uno, then I tried moving the setup to the nano, and here's my problem:
both sender and receiver when started or reset often fail at
LoRa.begin command (show the failed string on the serial) sometimes they manage to begin their loop.
on the sender it looks everything fine, and messages are being sent (sometimes they stop for several seconds, and then continue sending)
on the receiver the messages received are extremely long garbled strings,
1:37:56.542 -> LoRa Receiver 11:37:56.575 -> Starting LoRa failed! 11:37:58.762 -> LoRa Receiver 11:37:58.797 -> Received packet 'a00aaa000a0aaaaaaa0!⸮aaa⸮Baaaa⸮a⸮⸮⸮Ca ⸮⸮⸮⸮A⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮`y⸮^=^8⸮ ⸮NF ⸮a ⸮$ '#⸮aaaaaaaaaa⸮ ⸮NF @B1⸮⸮⸮D⸮⸮⸮⸮⸮⸮D⸮⸮⸮⸮⸮t`GC0⸮⸮⸮ @@0 x⸮⸮
and it seems to receive data even when the sender is off.
any clues of what could I be doing wrong here?
