Hello,
I'm struggling to connect to an MQTT-SN Gateway when the device is configured for low power. Currently using MAC-OS Catalina 10.15.3, SES version 4.42 and have tried Nordic + Thread SDK's version 3.2 and version 4.
I can't register an MQTT-SN device when the thread_instance_init is called with ".radio_mode" set to "THREAD_RADIO_MODE_RX_OFF_WHEN_IDLE" If I build the project with this configuration, the gateway configuration fails and returns "app: MQTT-SN event: Gateway discovery result: 0x3"
I can change the radio mode to "THREAD_RADIO_MODE_RX_ON_WHEN_IDLE" and it all works as expected, but the current consumption is unacceptably high for my proposed application. I have looked at the gateway configuration on my MQTT-SN gateway and I don't see anything obvious that could change here to solve this issue.
Ultimately, I guess I'm asking"
A: Can other people successfully register/publish/subscribe to MQTT using the "thread_mqtt_sn_sleepy_publisher_pcba10056" example project?
B: If not, is there a workaround for this to be able to use MQTT-SN as a SED?
Thanks and Best Regards,
Roger
