How to switch between BLE and SMAC/Zigbee modes on KW4x

[ignisuti_]

Hello,

Our team is trying to develop a product with the KW41Z that switches between BLE and SMAC. We've dug into some of the demo projects that do both BLE and Thread, but it's not apparent how the switch over is made.

We see that the demo project calls XCVR_Init with BLE_MODE and XCVR_ChangeMode with ZIGBEE_MODE, but we don't see any calls to XCVR_ChangeMode with BLE_MODE as expected.  So, how does the radio switch back and forth between modes?

Can someone please explain which function calls are needed?

Just wanted to post what we found encase someone else has this question.

We approached this assuming we'd need to manage the switching between BLE and SMAC in our code. The radio on the KW41z appears to be setup more as a peripheral of the MCU where once you correctly setup the registers, the hardware handles the switching for us.

We now have BLE working simultaneously with SMAC, both transmitting and receiving.

Lastly, I wanted to point out that we're pretty impressed with this device. We've used the Segger SystemView tool to analyze the CPU usage consumed by our simple project and see that it's only consuming 2% of the CPU.
