Hi,

every couple of minutes the wlan connection is lost. Is this maybe a buffer runs full?

Can't reproduce. Mine is running since month without any reboot.

It is true, that the ESP is rebootet, when the Wifi Connection is lost. If the WIFI is lost, there is no reason to operate further and for me it is enough, that the device reboots and tries to reconnect to WIFI.

Maybe a Power-Issue?

Hi!

I'm having the same issue. I tried different scan times. The connection gets lost avery 60-65 messages.

gnome4711 commented 2 years ago

I printed the free memory to serial. The memory decreases after every scan. when its below 28k the conection gest lost which causes a reboot.

Hi, I solved this for me me by cutting out the part where the manufacturerdata is inserted into the json string. I guess the 'myData' variable (its content) franctured the memory somehow. But I'm not sure if that is even possible.

Maybe this gonna help someone in the future.

greets
