today we build a custom version ,the firmware name is:j10_powermode_1btn_240312.hex. will update to github later

features as below

1. hearing aid algorithm unchanges
2. 1 button (DIO5） ，short press to change volume ,long press to change mode ,very long press( you can press until you hear tone) to enter power sleep mode , and when you are in power sleep mode, you can press dio 5 until you hear tone ,and the device restore normal mode
3. volume from 0 - -21 db ,it has different tone when volume reach maximum ,mininum
4. low battery alert is enabled , you can disable it in web ,but in this version we disable ble notification about the low battery
5. when device start , the firmware will make DIO 11 output high ,see this diagram

How to flash the firmware

0: I think when you flash , u need long press the POWER KEY to power on the chip until you complete flash ,or you power on VBAT directly

2. you need particular action because we have sleep function

Sometimes the firmware in RSL10 cannot be successfully re-flashed, due to the
application going into Sleep Mode or resetting continuously (either by design
or due to programming error). To circumvent this scenario, a software recovery
mode using DIO11 can be implemented with the following steps:

1. Connect DIO11 to ground.
2. Press the RESET button (this restarts the application, which pauses at the
   start of its initialization routine).
3. Re-flash RSL10. After successful re-flashing, disconnect DIO11 from
   ground, and press the RESET button so that the application can work
   properly.

后记:

当所有完成以后，我们通过网页修改了BLE名字，重启，确认修改生效后，点'backup all modes'完成备份
