https://devzone.nordicsemi.com/f/nordic-q-a/75191/bluetoot-mesh-used-channelIn bluetooth mesh only 3 channel are used.There is a way to use mesh with an extended number of channel. Because in some industrial enviroments fading is very heavy and so is better to use more then 3 channel. For exaxmples 12channel So can we defineen-USTelligent Community 13Tue, 18 May 2021 10:37:05 GMThttps://devzone.nordicsemi.com/thread/310103?ContentTypeID=1Tue, 18 May 2021 10:37:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d530d94a-4021-4376-a4de-606c35811f73Simonr<p>Hi</p> <p>As David says, changing to the Coded PHY (125kbps) might be a good idea, as it will use secondary advertising channels to transmit data on, so I would also suggest checking out the case David links to.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/309908?ContentTypeID=1Sun, 16 May 2021 16:42:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:40c185e9-e148-40d2-9cb5-28ee4830db7edaviddedwin<p>Would it make more sense to switch the mesh to a PHY like 125kbps ? They have been reported to have better performance in some industrial environments and its relatively simple to make that switch.</p> <p>You can look at this thread to look at the changes that can help get you running on 125kbps</p> <p><a href="https://devzone.nordicsemi.com/f/nordic-q-a/29813/change-phy-in-mesh/118379#118379">devzone.nordicsemi.com/.../118379</a></p><div style="clear:both;"></div>
