Question

Dear forum,

I bought a fmb001 and I configured it to send data to a custom server (a wrapper of https://github.com/Disposer/Giparus/).

I received the data packet correctly and I sent the number of data packet but the next tick the device resend to the server the same data.

What can I check to solve my problem?

Best regards

Hello,

Thank you for your question,

Could you make sure that the server response to the device is sent? The device will not send a new packet until the previous one was accepted.

Please follow the information on communication protocol description in our wiki page:

Also make sure that a new record is acquired more often than the send period. This can be checked in the configurator section "Data acquisition".

Regards.

I checked and I found an error in the code.

When I accept data from a module (after receiving the IMEI), I send an integer (4 bytes) instead of a single byte.

Is this a normal behavior that a wrong response for the IMEI approval doesn't refuse the data packet but it although send that without checking the ack?
