B4R Question ESP32 & MQTT Connect and reconnect

[viriato]

Dear All,
I am using this example https://www.b4x.com/android/forum/threads/mqtt.65669/#content as a starting point and I added a Timer to blink a LED , publish the ESP32 internal temperature and also detect PIN change state , example attached
But I have an issue with scenario 3 when disconnecting the MQTT broker , timer is not working anymore and the pin event is not working either (hang-up about every 40 seconds)
Tests done :
1- Program start and everything is connected - OK works fine
2- Program running disconnect network , router (WiFi OFF) - "Disconnected" , "Trying to connect again", TIMER and PIN Change state are OK, Work fine during the reconnect process ,
then re-connect network router (Wifi ON)- program reconnect again everything works fine
3 - Program running everything OK, disconnect MQTT Broker (Mosquitto on Raspi ,unplug network cable ) - "Disconnected" , "Trying to connect again" , TIMER is blocked ~ 40 secondes ,PIN Change state is not active ,detected only ~40 seconds after switch pushed, then re-connect MQTT Broker (plug cable) - program reconnect again everything works fine.

Any idea about why Timer is blocked ? Any suggestion to make it working ?

Thanks a lot

This is the default behavior of the wifi client. It blocks until the connection succeeds or fails.

Worth trying to ping the server before calling connect: https://www.b4x.com/android/forum/threads/esp8266-ping.74748/#content
I'm not sure whether it will block or not. You need to test it.

Hi Erel,
Thanks for the feedback
I tried the ping example but I am using ESP32 not sure it works and got an error , see below


Kind regards

Hi ,
It looks like there is a different ping version for ESP32 https://github.com/marian-craciunescu/ESP32Ping
Can this be implemented into B4R ?
Thanks

Et voilà

ESP32 Ping

This is a B4R-ESP32 portation from https://github.com/marian-craciunescu/ESP32Ping Rename to rar and use winrar for decompression because rar attachment are not allowed. Sub Process_Globals Public Serial1 As Serial Private ping As ESP32Ping Private wifi As ESP8266WiFi End Sub...
