    • RE: RFM69 MQTT gateway radio send loop

      After more investigations I believe the problem is caused by a mqtt server connection timeout.
      By default the gateway tries to send the radio message 5 times. If I lower the number of retries , 2 for example, no more loop. Probably now much more then 25 messages cause a loop.

      For testing I added _MQTT_client.loop() in transportSendWrite() (MyTransport.cpp) and, no more loop with default 5 retries.

    • RFM69 MQTT gateway radio send loop

      Hello all,

      I recently started a migration process from LowPowerLab library and gateway to MySensors network and Home Assistant controller.

      After playing with a ESP8266 as Mqtt gateway and a few test nodes with RFM69 radios, all working ok, I encountered a problem. Basically if the gateway tries to send 25 messages over the air and none of them are acknowledged the mqtt connection is restarted and the gateway starts resending the messages and enters a loop. Evidently this happens with retained mqtt messages.

      To make things easier I will start explaining with a simple setup:

      Default ESP8266 gateway sketch, only mqtt parameters, radio setup modified.
      A relay node with 25 outputs.
      Everything works ok.
      The mqtt messages look like this:

      And it goes in a loop.
      I tested with ESP8266, ESP32s, Mysensors Master branch, Mysensors development branch.
      No change.
      (esp8266 somethimes goes into panic mode)

      In my opinion any amount of failed consecutive radio messages should not force a mqtt server reconnection.
      If there are fewer then 25 messages, lets say 24 messages and the 25th comes after a while, no problem. I have a problem when in mqtt queue there are more then 24 consecutive messages that cannot be acknowledged.
