KCS firmware - MQTT LWT?

[Witwicki]

i have tested send command control DAC , it's OK. 

It seems to be a bug

send this on the /set topic from board start up in order

("dac1":{"value":50})     < This works

{"get_datas":{"value":true}}   < this works

("dac1":{"value":0})    < this also works

{"input1":{"value":false},"input2":{"value":false},"input3":{"value":false},"input4":{"value":false},"output1":{"value":true},"output2":{"value":false},"output3":{"value":false},"output4":{"value":false},"adc1":{"value":0},"adc2":{"value":0},"adc3":{"value":0},"adc4":{"value":0},"dac1":{"value":0},"dac2":{"value":0},"sensor1":{"temperature":-100.0,"humidity":-100.0}}    < this works, switching on a relay


("dac1":{"value":50})   < This now fails and requires the board to be reset
{"get_datas":{"value":true}} < will also now fail

Sending the large payload seems to break the board untill reboot
