I am developing a project for nRF52833 using nRF5 SDK. In this project I am trying to update firmware via BLE DFU. I got some of the project codes from the ble_app_buttonless_dfu example. I used the S140 in the project and I aim the device to work both as BLE Central and Peripheral.
For BLE DFU, I am using the BLE application in nRF Connect for Desktop, with nRF52 DK is connected to the PC. I am trying to update the nRF52833 through this device. First I connect to the device, then I become a pair with bonding. After this step, I upload the .zip file I prepared from the "Start Secure DFU" button, but I get an error in the nRF Connect application.
Error Text: DFU failed with error: Unable to find characteristic 8EC90001F3154F609FB8838830DAEA50 for service FE59 on device E8:C9:A3:16:0E:81.0.
What can i do to fix this problem?
Below are RTT logs and nRF Connect logs.
