Hi Kim,

Yes, it's most likely me :)

As I mentioned, the softdevice was made to make it's simple for the application to handle BLE protocol. Linklayer is not fully accessible from the application. You can initiate the process (connection parameter update, encryption request etc) but you don't have full access.

Hello Hung,

Thank you for reply.

First of all, It seems like i watched your webcast on youtube. Am i right ?

Actually, i am developing a BLE link controller and starts to use the nRF52DK and S132 as a counterpart for verifing our link controller operation. That is the reason for why i want to access link layer function in nrf52 and S132. Is there any problem for you to answer to my question with it ?

Thank you.

By design, it's our Softdevice stack (S132) handles most of the link layer procedure. You as the application has some control over the process, for example sending connection parameter update request, sending connection termination, sending encryption request. But the rest is handled by the softdevice.

May I ask why you want to access link layer ?
