High,
I have a problem with MQTT JSON data send to a Node-red frontend ...
After some time (usually about 10 to 15 minutes) and although my sensors produce valid data(!) - in the serialized JSON Data some values change to 'null' data!
Just to clarify, are you asking for help with the code that runs in some unspecified device, or is this a problem that you think is caused by node-red?
High Colin,
you are right.... the problem is not caused by Node-Red ... it is caused inside ESP32 serializing sensor data... please apologize - I should post in the ESP32 forum...
Thanks, Alf
High,
I'm almost sure that the issue is caused by how the ESP32 handles the buffer data which it used to serialize JSON data ... so this is not a Node-Red problem... I should post it on a ESP32 forum I guess...
Thank you,
Alf
