HID: Error: Error: ERR 0x8 (INVALID_STATE) (:3068)

How do the pairing settings usually look like when HID is set to Keyboard + Media?

I'm not sure I understand the question, but that did get me thinking - hidcam seems to do NRF.sendHIDReport([1,code] and you're doing NRF.sendHIDReport([0,code] - does that make a difference? It could just be the order of the info you have to send out is different to normal with kbmedia
