Not sure if at all related, but I have occasionally noticed potential memory leaks in the MQTT library or use of it resulting in OSError with out-of-memory.
Whilst not pretty, periodically (e.g. on a thread or async) running gc.collect()
did the trick...
I've since moved to a new (asyncio) implementation since this MQTT library leaves a lot to be desired. It can be found here: https://github.com/nznobody/micropython-umqtt.uasyncio2. This is derived from micropython-umqtt.simple2/robust2.
Hello everyone,
i am using the mqtt library to publish some telemetry data to an IoT platform with a pycom microcontroller. But mqtt stops publishing data exact after five minutes even though it is still connected to wlan.
I am sharing the piece of code that calls mqtt client and the library
Connecting wlan:
wlan.connect('my wlan', auth=(None,'my password'), timeout= 50000) #even though i changed this timeout it didnt solve my problem
My credentials (for iot platform)
server = 'my server' port = 1883 id = 'my id' pw = ‘acces token’ topic_publish = 'v1/devices/me/telemetry' dict={}
Creating a client:
Client = MQTTClient(id, server, port, pw, pw) time.sleep(2) client.connect()
Publishing in the loop:
While 1 encoded=ujson.dumps(dict) client.publish(topic_publish, encoded) time.sleep(1)
Thank you all in advance!
