SX1262 and Pico2 OTAA join issues #1633

Description

@reyes73a

Hello,

I am trying to run the [otaa_temperature_led] example and I am having join issues. I am using the [Waveshare-Pico-LoRa-SX1262-868M] with a Pico2 board. I am also using US915 as the region. I can see the Join Request arriving at the gateway and a join accept being issued. Normally, this would notify the Pico2 that the join is complete and move on with the rest of the program. However, even though the Join Accept is being issued by the gateway, the Pico2 continues to send Join Requests non-stop:

=========== MLME-Request ============
MLME_JOIN
=====================================

STATUS : OK
....

=========== MLME-Confirm ============

STATUS : Tx timeout

=========== MLME-Request ============
MLME_JOIN
=====================================

STATUS : OK

I can also change the devEUI on the SX1262 and, as expected, the gateway sees, but rejects the join request.

The fact that the join request is seen and processed by the gateway confirms that the SX1262 is being commanded correctly (SPI pinouts). Could this be due to a join delay parameter issue or something like that? Any thoughts? Any help would be greatly appreciated...
