After a bit of searching, I found this "Nordic Devzone: Join existing Zigbee network with light bulb example" which leads me to believe that the default Zigbee channel is 16.
Is that still the case for the examples I'm using from SDK V2.2.0 ? If yes, then where is the `#define IEEE_CHANNEL_MASK` setting that this post mentions? I can't find it and would like to change it to either searching all channels or limiting it to channel 25.
If that doesn't work, I'll explore other options. For context, I'm using Zigbee2MQTT with a CC2652P2 coordinator. As far as I know, this is just using standard Zigbee.
