Hi,
This is slightly off topic (more software than hardware but as this is a
very active group, I'm hoping someone might happen to know.
The Micro:bit has a 2.4GHz radio that can either support a Bluetooth LE
stack or be used to send raw datagrams on any one of 101 channels from
2400-2500MhZ (1MHz steps)
https://lancaster-university.github.io/microbit-docs/ubit/radio/#setfrequencyband
Is there a simple way of using the Bluetooth radio in your average linux
PC/Laptop/USB BLE Stick to send and receive raw datagrams on a fixed
channel? ie underneath the B(LE) stack?
Cheers,
Tim
More detail:
Googled around and I don't see a way to get under the stack in userland.
Why? Because the BLE Micro:bit stack costs 12k RAM and the device has
16k. Simple radio datagram would be more that adequate for my needs, but
I need something to act as a hub and to act as a controller.
It's occurred to me I could use another Micro:bit talking to a linux
machine over the UART pins, but I was just wondering if it was practical
to cut out the middleman?
