Question about CC2540 RF registers

Other Parts Discussed in Thread: CC2540, CC2530

Hi sir,

I plan to use CC2540 in my project. However, unlike CC2530, I didn't find any information about registers that control RF part of CC2540 in the user's guide (swru191b), only status registers are available. Since the BLE stack is not open source, it means that both hardware and software of CC2540 are closed. I worry if problems are encountered during development, it would be very difficult to position the problems and do debugging.

Can anyone explain why the application is not allowed to access RF registers of CC2540 directly (said in the user's guide)? How to make debugging easier if neither the RF registers nor BLE stack source code is available?

Thanks!

Hello,

One of the reasons is that our stack has been qualified by Bluetooth SIG, and any modification to controller or host stack generally means it would have to go through qualification again. Note, that OSAL and HAL source is avail, a free sniffer is avail, and RF studio can access RF directly.

Br,

Thank you very much for replying! I think it will give me more confidence if the stack pass Bluetooth SIG certification.
