When using the ready-to-use project located at:
STM32CubeWL/Projects/B-WL5M-SUBG1/Applications/Sigfox/Sigfox_AT_Slave/
and sending any type of uplink message with the downlink flag enabled (using any serial terminal/x-serial connection tool), the following issue occurs:
- The AT slave correctly receives and collects the downlink message from the receiver.
- However, when forwarding the downlink payload to the user via the AT interface, the payload is printed incorrectly.
Although the downlink payload size is 8 bytes, the application prints the array as if its size were 8 * 2 bytes. As a result, an additional 8 random bytes are appended to the end of the printed message.
This behavior suggests that the array length is misused during formatting/output (likely confusing byte length with hexadecimal character length), causing unintended memory content to be printed.
Expected Behavior
Only the actual 8-byte downlink payload should be printed.
Actual Behavior
The output includes the correct 8-byte payload followed by 8 additional random bytes.
Please review the payload printing logic in the AT slave project and correct the array length handling to prevent extra memory from being printed.
