 TODO:
 
 - AP mode (creating an AP)
-- GPIO support (used for the Pico W LED)
 - Scanning
 - Setting a custom MAC address.
-- RP2040 PIO driver for the nonstandard half-duplex SPI used in the Pico W. Probably porting [this](https://github.com/raspberrypi/pico-sdk/tree/master/src/rp2_common/cyw43_driver). (Currently bitbanging is used).
-- Using the IRQ pin instead of polling the bus.
+- Investigate why can [this](https://github.com/raspberrypi/pico-sdk/tree/master/src/rp2_common/pico_cyw43_driver) use higher PIO speed. 
 - Bus sleep (unclear what the benefit is. Is it needed for IRQs? or is it just power consumption optimization?)
