MQTT auto disconnected after KeepAlive time
HoangPhuongPKH opened this issue · comments
Hi all,
Sorry about my English,
I'm working with MQTT and STM32, FreeRTOS and lwIP
I followed this a example
https://github.com/eziya/STM32F4_HAL_ETH_MQTT_CLIENT
No problem if publish to STM32 topic subscribed every second.
But, if I connect to broker (mosquitto), then do nothing, after 60s keepalive, STM32 send PINGREQ and moquitto send back, but I debug that STM32 did not recevied PINGREQ and then disconnected.
In this example, if STM32 reconnect if disconnected, but at 4 times, it can't connected.
Anyone can help me, thanks!
You must be able to determine where the broker response gets lost, "STM32" is not the name of a module, analyze your application and determine where you have the problem. Then
If you have a problem with an STM32 application, place an issue in that application repo, or go to an ST forum and ask there
If you have a problem with lwIP, go to the lwIP forum and ask there
If you have a problem specific to Paho, then ask here, please properly describe what you send, what you get, what you expect to get, and why.
