BLE MESH Stack(2.0.1)Light Switch Demo Roundtrip Delay getting higher between client and server

[Nikunj Patel]

Hii,

I am currently using two nRF52832 SDK boards to implement text message exchange with another nRF52832 SDK board via BLE Mesh SDK 2.0.1.

However, when I try to increase the frequency of sending the command the communication seem to choke. and i'm getting Roundtrip Delay higher between client and server.

Roundtrip calcualtion of 5byte send and receive  sheet is below

 

Round trip calcualtion of 11byte send and receive  sheet is below

How to reduce round trip delay time please suggest me ASAP.

Thanks,

Nikunj Patidar

Hello,

 

Sorry for the late reply. We are quite short staffed due to summer holiday here in Norway, so there is a little longer response time now, unfortunately.

What is the size of your Mesh Network, and how often do you send the messages?

When you send the 11Byte message, I suspect that it is split into several messages, and hence will increase the roundtrip time. 

Check out what Thomas and leonwj wrote in this case.

 

But yes, how many nodes are there in the network, and how often do you send the message?

 

Best regards,

Edvin

Hi Edvin,

Thank's for reply me..!

        i want to calculate Roundtrip delay between client and server no other node in mesh network. However, when I try to increase the frequency of sending the command the communication seem to choke.

light switch example code(Mesh 2.0.1) is modify just i add simple message model.in this code.

Thank's
