Been working some more on this and I believe I've discovered the root cause.
It appears as though the ABZ module is actually receiving the confirmation OK, however, the AT+CFS=? was returning the wrong answer.
Compared to version 1.1.1, there has been a line removed from Lora.c which would appear to be essential to getting a correct answer. I'm not sure where this change originated as I do not have access to 1.1.2 or 1.1.3.
Within McpsConfirm() the first line in 1.1.1 assigned the confirmation data stored in mcpsConfirm to lora_config.McpsConfirm. It is
lora_config.McpsConfirm that is checked when AT+CFS is queried, however, it remains null as it was never assigned to.
Adding the following line back into McpsConfirm() returns expected functionality:
lora_config.McpsConfirm = mcpsConfirm;
My concern is that this line was removed for a reason, so maybe this is not the correct way to return functionality? Perhaps instead mcpsConfirm was meant to be checked in lora_config_isack_get() and this change was forgotten?
Feedback would be very gratefully received!
Ben.
