GATT CONN TIMEOUT

[mijiale]

Hi all

nrf52840 Development board,sdk is nRF5_SDK_15.2.0_9412b96,PC is windows 10

When I run the demo of ble_app_hrs on my development board,I use nrf connect app to connect my devcie,the connecting will disconnect.

From the nrf conenct we can see that the error is "GATT CONN TIMEOUT" and I print the log of the error code is 34 that express BLE_HCI_STATUS_CODE_LMP_RESPONSE_TIMEOUT

There is another point to pazzle me is that this situation only happens when I use the phone of HuaWei,other phones just like XiaoMi and HTC will not happen this situation.

Hi

This is probably the same compatability error that caused the previous error. As I said we are working on patching this issue on all Android phones. Could you please specify which Huawei model you are using? Also do you know if the data write still happens even though you don't get the confirmation? 

Best regards,

Simon

Huawei mate9,honor 9,Huawei P20 pro and so on. All Huawei phones used to test for me have this issue.
