Can Zigbee coordinator and Bluetooth host run together on nrf52840

[koal]

SDK used ：NRF Connect SDK

MCU:NRF52840

Problem:In the NRF Connect SDK, I only see the dual protocol of Zigbee End Device and Bluetooth slave ("light_switch" example).Is there a possibility of Zigbee coordinator+Bluetooth host? If possible, what should I do?

I really hope you can answer this question. thank you！

Hello,

Yes, that is theoretically possible. You would just have to be a bit careful regarding commissioning etc., as BLE activity can interrupt the ZIgbee activity.

I believe that is why it might involve modifying a few files.

Do you have any relevant examples or reference materials for quick implementation，Thank you again

I thought it would be as easy as using the overlay file that you already get with the other samples that are supported for BLE coexistence to a higher degree. I just tried building it with the configuration overlay file that comes with the light switch sample now, and that seems to work.

Try building the network coordinator sample with this overlay for instance:

# BLE configuration
CONFIG_BT=y
CONFIG_BT_SMP=y
CONFIG_BT_PERIPHERAL=y
CONFIG_BT_DEVICE_NAME="Zigbee_Switch"
CONFIG_BT_DEVICE_APPEARANCE=833
CONFIG_BT_MAX_CONN=1
CONFIG_BT_MAX_PAIRED=1
CONFIG_BT_PHY_UPDATE=n

# Enable the NUS service
CONFIG_BT_NUS=y

# Enable bonding
CONFIG_SETTINGS=y
CONFIG_BT_SETTINGS=y

# BLE uses ECB peripheral directly
CONFIG_CRYPTO=n
CONFIG_CRYPTO_NRF_ECB=n

For further reading, have a look at the section on BLE coexistence from our light switch sample, and this page on coex in general.

Thank you very much for your answer，I am already able to implement the BLE slave+zigbee coordinator function, but there is no specific example in the SDK instance on how to implement the BLE host+zigbee coordinator function. I hope you can provide suggestions. Thank you!

Hello Koal,

I was just looking through some old cases and found this. Did you get the answer you were looking for? 

When the case gets a "verified answer" it normally dissapears from our view here.

Yes, I implemented this feature by changing the kconfig file，Thank you
