how to set only 1 advertisement channel for mesh?

[swap007]

Hello devzone,

There are 3 {37,28,29} channels for advertisement & i want to advertise only on 37.

Soft: Nordic mesh v1.0.0 stack & pca10040 nrf board, light switch example.

Try 1

I saw a function set_default_advertiser_configuration() (in /mesh/bearer/src/advertiser.c) which leads me to nrf_mesh_defines.h has a #define NRF_MESH_ADV_CHAN_ALL {37, 38, 39} I changed the values to 37 & servers unable to provisioned, am i missing something to configure to advertise only 1 channel? Thanks

Try 2 

mesh/core/src/core_tx_adv.c in core_tx_adv_init() i set_channels after advertiser_instance_init

set_channels.channels.count = 1;
set_channels.channels.randomize_order = 0;
set_channels.channels.channel_map[0] = 37;

advertiser_channels_set(&m_advertisers[CORE_TX_ROLE_ORIGINATOR],&set_channels); 

Unfortunately, mesh stack unable to initialize.

What seems weird is that you are getting the servers provisioned on the first try. This makes me believe that everything you have done is correct. What are you doing different on the second try? Have you tried debugging the client on the second try or running two rtt viewer windows (one for client, one for server) to see where the issue lies?

In first try, problem is servers does "not always" provisioned. So, there is always uncertenity for network establishment. 

In second try, i set channel 37 wherever i see advertiser_instance_init().

(I havnt try rtt windows to debug)

Thank you.
