nrf52832     SDK14.2       s132_nrf52_5.0.0_softdevice     PCA10040       ble_app_hids_keyboard  

I modify the project : 

two  service :  one  is   hid   another  is  different  hid_1 

press button 2  init  hid

presss button 3  init  hid_1

connect  the  android  phone , press button2   reset ,and ,init  hid;  press button3   reset  ,and, init  hid_1, reconnect  the phone,

turn  off and on the bluetooth(android  phone),but I can‘t receive   BLE_GATTS_EVT_WRITE(gcm_ble_evt_handler),  I  enable  the  NRF_SDH_BLE_SERVICE_CHANGED

I  can’t  know the reason,  but  SDK15.2   it  succeed,  why?   How  can  i do?

Hi

Thanks for the updated instructions. I've been able to recreate this issue now, on an Android 7 device as well, so it is not an Android 9 "exclusive" issue. Your project had to be built in Keil to make buttons 2 and 3 work properly and was the reason I couldn't reproduce it. I will get to debugging it now.

A few questions:

• Are there any differences between gatt_mode 0x00 and gatt_mode 0x02 in your application?
• Do you get this error every time you turn off the Android Bluetooth? 

Also, please post any updates on what you've accomplished/discovered as well.

Best regards,

Simon

1  The difference  between gatt_mode 0x00 and gatt_mode 0x02  is the hid init funcition.You  can  compare them.

2  Yes，and you can try more.

3  It  can works well by using SDK15.2.

Thanks，I expect your reply!
