Looking for freelancer to develop firmware for Qualcomm QCC5181

MattUMA

I have a prototype using standard firmware in a BTM581. This has BT/USB with Bluetooth as the priority. I dont need help with hardware on a fimrware build.

The standard firmware means BT is always on, I would like to be able to specifically switch between BT and USB.

So either the firmware needs to have USB as priority (and then I just switch on/off the USB Vbus to make the module flip between BT and USB) or it needs a way to switch between BT/USB via a GPIO.

The other requirement is that all the standard firmware I have seen is built on the headset firmware so the USB declares as a headset not a speaker. I need the USB to declare as a speaker.

I have a document of the other items (GPIP, PID/VID etc.) which are all not complex as close to what you see in many projects.

Please contact me if you have the knowledge to do above. Note I have a Qualcomm account but I have no expertise in the ADK myself (beyond basic things).

这个问题并不复杂，可以通过PIO切换USB/BT模式。
