Essentially, I'm trying to figure out how I can use Bluetooth Classic using the on-board U-blox w102 Wifi/Bluetooth module. I'm assuming that SerialNina and SerialHCI are somehow connected to it and maybe the way to use Bluetooth Classic on the Nano RP2040.
From this, I'm assuming that SerialHCI can be used to control BLE and SerialNina updates the Wifi's firmware. Am I right about this? If so, what part of the Nina-w102 module is SerialHCI connected to?
