Dear Sirs, We compile the bootloader in dfu folder, sdk 10.0.0, with IAR, and download on 51822 QFAA chip. When trying the DFU function with MCP tool with version 3.10.0.14, we always receive the error "Error during firmware upload. Disconnected from device while waiting for notification from device". Capture the log fragment from the MCP tools as below.

I try some solution on forum, such as adjusting timer of interval, supervisory timeout, but still not work. And I also try the DFU in "nrf Toolbox" on ios. The error "DFU, the connection has been lost" will occur when starting to upload the firmware, 0%. Any idea??
Thank you in advance.
