(FOTA) java.lang.IllegalArgumentException:null value

Hi, not sure what is causing this error but it seems to prohibit FOTA from happening on my system…

The above two lines just keep on repeating every couple of seconds. Not sure if that means the node is in a reboot loop…

Typos ?

You’re right… It only worked the first time. The second test failed. I will experiment with different radio powers and packet sizes over the weekend (if time permits) and let you know what I find. Thanks for the support, it’s appreciated!

found: (in …\libraries\MySensors/drivers/PubSubClient/PubSubClient.h) #define MQTT_MAX_PACKET_SIZE 128

trying to override it with: #define MQTT_MAX_PACKET_SIZE 512 in the sketch

seeing progress now…

…and it worked, finally!
