How can you adjust the channel using the Zigbee SDK

It was the persistent config setting. The source code set the ERASE_PERSISTENT_CONFIG to ZB_FALSE and because I initially tested the three boards together in the light switch demo project the channel got fixed to 16. From then on it was picking it out of the configuration and ignoring anything I was giving it.

A rookie mistake I suppose but then again I am just starting out with this!

Having changed the setting and putting the channel number to 14 the demo switch was found by my SmartThing hub so now I can make some progress.

Many thanks for your speedy reply and help.

Hello,

Are you sure you don't have multiple definitions of IEEE_CHANNEL_MASK?

Try to only change the #define ZIGBEE_CHANNEL 11 in sdk_config.h (SDK\examples\zigbee\light_control\light_switch\pca10056\blank\config). Also, make sure that you erase the chip, either by using nrfjprog -e before programming the DK, or by setting "#define ERASE_PERSISTENT_CONFIG ZB_TRUE" near the top of main.c.

Let me know if it still doesn't work, but I tested it here. I didn't try to log anything, but the device was certainly not connecting to the network when it was using the wrong channel.

BR,

Edvin
