Problems encountered in USB application:

I guess there should be no problem in normal application scenarios (a fitter has several usb dongles, and a user only has one usb dongle, and a hearing aid only tries to connect 1 to several usb dongles), but in the development stage, we do encounter the situation that the usb dongle cannot be connected to the hearing aid or development board. device and an E7160 development board), it turns out that the usb dongle at the back is always disconnected. The following is our solution

1. Re-update the firmware of the e7160 by pressing CTRL while clicking Connect
2. Then press the button of clear bondlist on the development board. I guess this is the most important step.
3. At this time, use the usb dongle to connect to the 7160 development board again, and you can connect.

Reason description: There should be a bondlist table inside the 7160 development board (or hearing aid). The length of this table should not be long, such as 10 or 20. Every time a new BLE client (mobile phone, usb dongle, etc., one MAC address counts as one) will occupy a row of bondlist. When it is full, the new BLE client cannot connect.
