BLE 4.2 support on nrf52840.

[Anco2]

Hi

Does nrf52840 PD Kit support development of ble 4.2 standard applications?
If yes, how can this be achieved.

NB: I have 3 nrf52840 PDKs and wanted to use them for throughput comparisons between ble 4.2 and ble 5.

Hello,

BLE 4.2 and BLE 5 is quite similar. You can in theory call BLE 4.2 for BLE 5, only that it does not support the optional features, such as long range BLE or high speed BLE.

 

There is an example in our SDK, called ble_app_att_mtu_throughput.

Check out this guide.

 

Here you can switch between 1Mbps, 2Mbps and Coded (Long range),  as well as tune the other connection parameters.

The guide describes how to operate this example.

 

Best regards,

Hi,

Thanks a lot Edvin for the response.
I had already used the throughput example to get results for the different modes of operation.
So that mean i can use the results for 1 Mbps mode as results for BLE 4.2?
Advice accordingly.
Thanks and Warm regards

That is correct. 1Mbps is the "standard" BLE radio speed, which is used in BLE 4.2. BLE 5 introduced the options of 2Mbps and Long range (lower speed).

Okey, thanks a lot
