Little OT, yes it was a thing, but so far just bought Lenovo keyboard and an adapter for FCP tape. Meantime some BTstack "problems" with BLE HID was worked around then officially resolved (composite HID device). Little bit less OT: with sdp_rfcomm_query.c was no problem to connect to Bluetooth 2.1 Sony Ericsson phone's RFCOM server (actually spp_streamer_client.c was used to pair and bind first - it's made of rough edges, just to play with it) so Pico W could do all that AT commands stuff. Some older Bluetooth 1.0b was to old for CYW43439 (even Bluetooth 4.2 Samsung S7 wasn't able to talk with it). Anyway clients are working.
You might report that on https://github.com/bluekitchen/btstack/issues.I can tell these examples are not very finished yet. There's results of blind copypasting like this:
