Retaining last payload

General
1

Hi all,

I have a tcp modbus device that communicates to other devices via rf. on occasion we have rf interference causing communication dropouts.

Each payload is sent to a cloud. When the drop out occurs msg.payload will be sent = 0 causing inconsistent data on the cloud.

Is there a way of retaining a payload until the next successful connection & var is received?

Thanks In advance.

Maybe I don't fully understand the question, but would it be better to send nothing when the problem occurs, and send the next good data when it arrives?
