Concurrent Thread and Zigbee (with Wifi)

Is it correct that the chipset supports Wi-Fi together with both Zigbee and Thread at the same time (as coordinator and border-router)?

QCA4020 supports Wi-Fi together with both Zigbee and Thread:

Zigbee Co-Ordinator:
Zigbee Initialize
Zigbee SetExtAddress 000000FFFE00001
Zigbee form 1 0 16
Zigbee permitjoin 255


Thread Border-Router:
Thread Initialize 1 0
Thread UseDefaultInfo
Thread Start
Thread AddBorderRouter 2000:baad:beef:: 64 0 1 0x98
Thread RegisterServerData
Thread StartBorderAgent wlan1

Hi,

Thank you for the response, when trying this with the QCLI I get the following response:

ZigBee: qapi_ZB_Initialize returned -1 (ERROR)
that is when I first first initialize thread. If I first initialize Zigbee, I get this error when trying to initialize thread.
 
I use a Silex module.

I just got response from Silex that it is not possible to run Wi-Fi together with both Zigbee and Thread at the concurrently (so 3 protocols). Although it was confirmed here by Raja and should be possible as they use the same physical layer. It seems blocked in firmware.

If there is more information from Qualcomm or anyone who can confirm or contradict, I am interested.

Hi Steven, Apologies for the confusion.
4020 supports initialization of Zigbee and Thread both along with Wifi, however in case of communcation transmitting/reception of data QCA4020 supports either Thread/Zigbee along with Wifi as Thread/Zigbee shared the same 15.4 MAC layer
 
The error during initialization is due to resource allocation failure.
