frame-counter did not increment"

[henrytheshed]

I am running ESP32 Lorawan library on a LoRa WIFI 32 (V2) board. I am connecting to a RAK module connecte d to a raspberry Pi 4 running chirpstack gateway os. I am connecting using OTAA an EU868 region. Mostly I join then the payload messages update correctly and are displayed in the data section of the Chirpstack applications server. However from time to time I get the error: "frame-counter did not increment". Then the next messages contain the same erro usually 5 messages. Then I get a Join and the messages are accepted again.

I note that the library from which the HELTEC library was ported appears to have been updated more recently and doing a compatison of files shows they are very different now. I don't know if they have diverged. The original files used to port are showing changes a couple of months ago to fix a frame counter increment problem.

I also use this library with a number of CubeCell boards.

Might it be possible to review the libraries and do some updates?
