https://devzone.nordicsemi.com/f/nordic-q-a/76095/bluetooth-mesh-channelI see that I can USE BT MESH in an application . Can I encrease the number of advertisingh channel adding some secondary advertising channel? May I do that in this way ? With Zephyr May I do that?

So no you can&#39;t increase the number of channels/secondary channels use in BT mesh. You can enable extended advertising to get significantly better performance for mesh advertising.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/314273?ContentTypeID=1Tue, 08 Jun 2021 16:08:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:238ea658-fb4e-4757-898a-61f5a6dd2f16novello<p>I would like to use more then 3 channel, To reduce the effect of the noise. So my question was may I increase the number of channel used&nbsp; on BT mesh ?I can reduce the bitrate but in that case wich is the band occupation&nbsp; is still less the 1% ?The other point is if I have more channel available available I can increase the security?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/314235?ContentTypeID=1Tue, 08 Jun 2021 13:33:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9eb1d3d7-9f84-4775-be9e-264c7bf0a7d8Mttrinh<p>Hi,</p> <p>It&#39;s not clear what you are trying to do here. Do you want to run mesh and normal BLE concurrently? Why do you want to increase the secondary channels? Can you elaborate on that you are trying to achieve?</p><div style="clear:both;"></div>
