It would be nice to have full range of cpu speeds at runtime for Pico W.

There was topic, and I've put standalone version ot BT example layout file. Here for the mouse: [mouse.zip](https://github.com/raspberrypi/pico-examples/files/11760664/mouse.zip). You can change BTStack example files there `.c` and `.gatt` for BLE...

There is [picow_bt_example_sm_pairing_peripheral](https://github.com/bluekitchen/btstack/tree/master/example/sm_pairing_peripheral.c) with corresponding `.gatt` file to encrypt characteristic data as well.

For example hog examples :P might be helpful as well, you can trace `hids.gatt` file and see how transferred data are secured with `ENCRYPTION_KEY_SIZE_16` and apply the same to for...

For me polarity = 1, phase = 0 works for both - with or without CS. Phase and polarity = 0 is the same like that, but without extra dummy...
