First steps

the WB55 Nucleo boards are in, and luckily ST ships them with a bunch of BLE-related examples, including one for an HID mouse profile. It doesn’t do much – one person gives the MCU a relative cursor position over serial, after which the MCU transmits the new position over Bluetooth to a connected computer – but it gives a good basis for what we’ll have to create. It also looks like a lot of the BLE-related stuff is taken care of for us within the ST libraries, so we (thankfully) won’t have to write any custom drivers or anything like that. On the hardware side, component selection is underway, though the capacitive sensors and antenna may be more challenging than we thought (mostly because none of us have experience with either of those).
