QoS configuration on ST67W

XP_LGE · ‎2025-09-26

Hi, i have bought a Nucleo-U575ZI-Q coupled with a X-Nucleo-67W61M1

i have upload the exemple ST67W6X_MQTT, after reading the doc i have complete the configuration and i run well.

I use it with mosquitto or nanomq brokers (same results) but on both the broker inform me than the QoS=0 (with publish and subscribe)

The documentation of the AT-command of ST67W indicate that i can use 0,1 or 2 for the Qos. In the exemple the drivers don't use the Qos and force it to zero. I have modify it but the result is always the same. I would like to use QoS=1 to be sure the message arrived. Have you an idea ?

I have verify than the broker accept all levels in the conf. I have also publish with MQTTX(with Qos=1) and the broker notify the good level of Qos

Hi XP_LGE,

Can you please test again with ST67W6X_MQTT project from latest release 1.1.0? QoS has been added into the application's configuration options (see ST67W611M1 Wi-Fi® – MQTT Demonstrations - stm32mcu).

Best regards,

Hi XP_LGE,

Could you test with X-CUBE version 1.2.0? It includes a fix related to QoS flags.

Best regards
