nrf51422 + nrf8001 or nrf51922 Hardware Question

Yes, you are right.

The nRF51922 is discontinued and will not go into production. The nRF51422 Rev 3.0.0 development kit is its successor which you can flash the latest softdevices, S210, S310 or even S110 and S120 BLE stacks also.

If you want to develop ANT+BLE, get the nRF51422 Rev 3.0.0 development kit. To make sure you purchase the right kit, and not the older nRF51422 kit with preprogrammed S210, take a look at this thread.

Now the nrf51422 has the S310 softdevice, this no longer applies isn't it?

Hi,

Thanky for your answer. I contacted my local Distributors, i hope they can sell me some Dev Kits :).

Best regards Nils

The S310 softdevice, which resides on the nRF51922 chip, enables both BLE and ANT to be used on the same radio.

For you question about where to get the nRF51922 development kit, it is addressed on this thread: http://devzone.nordicsemi.com/index.php/nrf51922-dk

Hi Stefan,

Thank you for your nordic support. This exactly what i wanted to hear :). So i will use the nrf51922 for my Project, gret that there is such an example using BLE and ANT at the same Time. But how is that possible, there is one Antenna and one Radio? Did you developed something like multiplexing the antenna?

I looked at mouser and othere Ditris but i can not found the nrf51922 Development Kit, where can i buy one. I know that i can not use my 51822 Dev Kit becaouse the 51922 SD is burned in. Will the 51922 cost as much as the 51422 and 51822?

Best regards Nils :)

Hi Nils

For nRF51922, BLE and ANT can run concurrently, i.e. you can maintain BLE and ANT connection at the same time. I would clearly recommend nRF51922 if you need both BLE and ANT. Having nRF51422 and nRF8001 will clearly have higher BOM and will most likely require more development effort from your side as you would need to operate two chips instead of one. It is also a benefit that it is fairly easy to use for nRF51922, any BLE example code from the nRF51822 SDK. Similarly, you can also use ANT example code from the nRF51422 SDK or your custom nRF51422 code for ANT communication on the nRF51922 chip. There is also available heart rate monitor example code for nRF51922 that uses both ANT and BLE at the same time. It receives ANT heart rate data and relays that heart rate data to a BLE central device via its BLE interface.
