Trying to run light lightness application

[shreyab]

hi,

I have developed light lightness model with the help of generic on/off and generic level model from the mesh SDK. And I have used these models by making changes in the light switch example, and used my light lightness in place of generic on/off.

Two things to note are, as i want to do initial testing, i have only implemented lightness actual related code, and i am not using generic on/off in my temporary test application because at this point I am not tessting any bindings,

Can a mesh developer please tell me any pointers or things that might get missed while developing the lightness model, app layers (for the above mentioned basic testing purposes).

All I'm trying see if the messages sent by my client are being received by the server with just logs (for now) on the server side, i am trying to send lightness_actual_set() and lightness_actual_set_unack() - with both these the client prints TRANSFER TIMEOUT, can anyone please shed some light on this.

I am using v310 of mesh sdk

Thanks!

I would suggest you to get familiar with the generic on/off model first. 

You can find out if a packet is sent by enabling log level to DBG1: LOG_LEVEL_DBG1 and allow logging from  ACCESS library: LOG_SRC_ACCESS. You should be able to see if the packet is sent (look for "TX:" ) and when a packet is recevied ("RX") 

An unack message shouldn't cause a transfer timeout, I'm not sure why that happens, could be related to how you implement your model. What exact function throws that error ? 

[shreyab]

no, sorry my bad didn't write that  correctly, set message gives the timeout error

You mean only the lightness_actual_set() caused timeout error ? If it's the case, most likely it's the server didn't reply to the client. Please make sure you implement the code to reply when you receive a set command. Please refer to the generic on off model.  

Also you need to check if the server is actually received the set command.

light_lightness_actual_set() gave a timeout error true, but set_unack() message also didn't the server.

how can we debug server not receiving any client commands? i don't get any RX either on the server side, are the packets being dropped? is the server not recieving them at all?

Which destination address you used to send the data to ? Have you made sure the server subscribed to the address you sending to (unless you are sending to the unicast address). They should be provisioned in to the same network. 

I would suggest to use the access layer directly to send test message. This mean you ignore the model layer. You can enable logging inside the access layer to see if the packet arrive at the destination. 

I assume you have tested the generic onoff example ? You can do your test (sending packets on access layer) on the generic on off example first before continue.
