I would like to be able to use USB to do field FW updates to my company’s BC127 based Bluetooth product.
I see in the documentation that you must do a write and reset to the “USB_HOST” property over UART and, and then I assume I will be able to interact with the BC127 over USB and do FW updates .
The problem is there is not much else information on the USB_HOST setting, and I am concerned about reliability as some have reported here they are not able to do USB operations once they enable USB_HOST.
Is there more information about this feature somewhere? Does this require special CSR drivers or anything like that?
