nRF52840 sales manager for Massachusetts, US

[Alberto]

I have reading lot of questions/answers about the nRF52840 and when asking for pricing and availability the answers is always "call to sales manager or distributor" , however, there is no information at Nordic website where to find it.

Can any one at Nordic provide this information, please?

Also, in one post is mentioned that nRF52840 will be available in Q3 2017 and another Q4 2017. What is the real Q3 or Q4?

Also, they said that ZigBee will be supported and will work concurrently with BLE and that it will be available on Q3 2017, is this true?

My point is all this different information is causing confusions.

Hi,

The official press release state production variants available in Q4 2017, so this is the correct timeframe. If you need more information about this, you should contact your regional sales manager. I will message you the contact details.

About ZigBee, no information about availability of this have been announced. There will be support for IEEE 802.15.4 with BLE running concurrently. This will be released soon (well before Q3), but this will be experimental until production variants of nRF52840 is available in Q4. Note that 802.15.4 is not the same as ZigBee. 802.15.4 specifies the two lower PHY and MAC layes that ZigBee runs on top of. If you want to try out 802.15.4, you can already try out applications running the OpenThread stack from Nest. OpenThread is an open-source implementation of the Thread networking protocol. Thread is another protocol running on top of the 802.15.4 PHY and MAC layers. OpenThread support the nRF52840, and you can find an example in the GitHub repository.

I'm sorry for the confusion, and hope this clears things up!

Best regards,

Jørgen

Yes, what he means is that the 802.15.4 stack (which is the one accessing the radio peripheral) will be able to run concurrently with BLE. If you want to run a ZigBee stack on top of this, it will still be concurrent with BLE. ZigBee is supported by the hardware, as the radio is 802.15.4 compatible, but it is not not mentioned in the post that a ZigBee stack will be available in Q3.
