nRF Toolbox DFU Operation failed about ios-nrf-toolbox

1. You are flashing s130 onto nRF52 device which is not compatible. For nRF52 the S132 should be used. But this should not matter, I guess, as the DFU bootloader does not know it yet. It would just brick* your device if successful.
2. Could you try with lower value of Packet Receipt Notification? You can set it in nRF Toolbox settings in Settings application. Set value to 1 first, then try higher values.

* - semi-brick, as you would be able to flash correct version using USB

Hi philips77, thank a lot!
I had try S132 or my zip file, it was still failed. Through breakpoints, it's failed in DFUService.swift
"func sendFirmware()", and got ErrorCallback as following.

(lldb) print report
(iOSDFULibrary.ErrorCallback) $R0 = 0x000000010041e410 iOSDFULibrary`partial apply forwarder for iOSDFULibrary.DFUPeripheral.(sendFirmware (iOSDFULibrary.DFUFirmware, withPacketReceiptNotificationNumber : Swift.UInt16, andReportProgressTo : Swift.Optional<iOSDFULibrary.DFUProgressDelegate>) -> ()).(closure #1).(closure #2) at DFUPeripheral.swift

@LtkDev is that crash using in that screenshot using our own bundled firmwares or yours ?

Please do the following so we can confirm where the problem is

1-Remove any bonded peripherals in the bluetooth settings.
2-Uninstall your version of nRF Toolbox.
3-Install nRF Toolbox from the app store.
4-Restart phone.
5-Launch nRF Toolbox.
6-Put your peripheral in DFU Mode
7-Select the bundled firmware hrs_dfu_s132xxx.zip

If that still doesn't work then something is probably wrong with your board, please try to flash it with nRF GO on your desktop with a compatible firmware and try again, let us know how things went

@mostafaberg Thank you so much! DFU is workable!
After reinstall nRF Toolbox and use another board with SDK v11 & s132 v2.0.0, it worked now.

Glad to hear it worked out!, let us know if there's anything else we can help with, for now I'll close this issue 👍
