B-072Z-LRWAN ACK

[emil28]

Hello,

I am using the evaluation board B-072Z-LRWAN with the example code provided by ST (STM32CubeExpansion_LRWAN_V1.3.1), the End Node project. Data is received on my LoRa server, messages are sent as "Unconfirmed". Now, I want to send "Confirmed" message, so I changed in the main.c the #define as follows: LORAWAN_DEFAULT_CONFIRM_MSG_STATE          LORAWAN_CONFIRMED_MSG

The server send a void message as an ACK, but it looks like the board never receive it. Nothing appears in my terminal, the callback "LORA_RxData" is not executed . Do I need to change other parameters in order to make the ACK works ?

Declared in "main.c"

Message received on the server and ACK sent:

ACK not received on the board:

Thanks.

I am also having a problem trying to find out if my messages have been confirmed. Did you get a solution to this?
