nRF5281x Advertising Extensions

[Olga Ermakova]

I wonder if the nRF5281x can work in the "LE Advertising Extensions" mode, which seems to be like in Bluetooth 5.0, when data is transmitted by secondary advertising packets over data channels without establishing a connection. For example, you need to transfer 1500 bytes in a chain of advertising packets as in the example. Is something like this implemented on the stack from nordic? where can i see examples? SDK?

Hi

The nRF52811 can use the S140 SoftDevice, which supports some, if not all, of the LE Advertising Extensions features. 

Unfortunately the limited flash memory of the nRF52811 means you will have quite limited flash left over for your application, so you have to take this into account when selecting the part for your project. 

Best regards

Hi

SoftDevice is the term we use for our RF protocol stacks, and we have some different version available for different chips and different features. 

You can find an overview of the SoftDevices here.
