Delay in listener

Hi,

I am using listener to send tag’s location data to the server. I am able to get the location data on raspberry pi but when I try to send this data to server, there is some unexpected delay.
Can anyone help me with this?

Thanks,
Hanish

Hi Hanish,

how do you get the data from the Listener and how do you send it to the server?
What is the “unexpected delay” in this case?

Sending messages back and forth is time consuming. People can help you but you need to be clear and specific. I cannot read your mind yet :slight_smile:

Hi,

I am receiving location data of multiple tags on listener using minicom. And I have written a python script to send serial data to mssql server.
By unexpected delay, I mean the time difference between data received on serial port and when the same data is received in database.

Thanks and regards,
Hanish

Hi Hanish,

in general the position which you receive on the Listener should be received also on the Bridge at the same time. The data then pass through the Kernel Module, the DWM Daemon, the DWM Proxy to the MQTT Broker. It should be within 100 ms max.

Is your MQTT Broker on the same IP network? How long is the delay which you do observe?
