dfu with encrypted connection(SDK 11). stuck in dfu_ble_svc_peer_data_set

[kibo]

Hi I am using sdk 11 and adding DFU to my application

My application always stuck at dfu_ble_svc_peer_data_set(&m_peer_data); in function 'static void dfu_app_peer_data_set(uint16_t conn_handle)'

Before asking a question I already saw this page and followed all comments. But it still stuck at same location devzone.nordicsemi.com/.../

Please help me. Thanks

Hi kibo,

Have you flashed the bootloader ? And in the bootloader the SVC call for dfu_ble_svc_peer_data_set is declared (as in our bootloader example).

Do you use device manager in your application ?

[kibo]

Yes, I use device manager. I use device_manager_peripheral.c file And I checked that dfu_ble_svc_peer_data_set function is in bootloader

Have you tried to test with the buttonless application ble_app_hrs_with_dfu in our SDK ? Could you state the steps you do when testing? start with programming the softdevice.

[kibo]

Yes, I tried ble_app_hrs with DFUexample. It works well. I use SAMSUNG GALAXY Note 5 and nRF Toolbox Here are my steps. Select my device and zip file then, press UPLOAD button

I printed all ble_event with RTT Viewer. I used SEGGER_RTT_printf function to print event id in ble_evt_dispatch function Here are my application's BLE event steps. 0x10 0x14 0x13 0x12 0x1A 0x30 0x19 0x12 0x50 0x50 0x50 0x51 I am not sure this information is helpful.

And sometimes my application stuck at dfu_ble_svc_peer_data_set function or GATT Error is occurred.
