Hi everybody!
I have the problem with MQTT using on my ESP32 - after about 2 minutes of my device working I recieve the messages about Heap decreasing. And after 20 minutes of working app is crashing.
The part of my code:
Timer.set(1000, Timer.REPEAT, function() {
MQTT.sub(topic, function(conn, topic, msg) {
print('Topic:', topic, 'message:', msg);
msg = JSON.parse(msg);
if(msg.devId==='host' && msg.cmd==='setTemp') setTemp = msg.temp;
}, null);
}, null);
The part of log:
