DFU OTA on iOS

[Cyril Hruscak]

Hi,

When trying to update an application using nRF Toolbox on iPad, I get the error as in this thread.

Turning Bluetooth OFF and ON does not help. On Android it works without any problems.

I'm using custom board, SDK v9.0 with SD v8.0.0 and bootloader from the SDK. The nRF Toolbox is version 2.4.

Is there something I need to set on iOS to make it work?

EDIT: According to BLE Sniffer it seems the iPad sends Reset System opcode if I understand correctly (see image).

Best regards, Cyril.

Unfortunately, I'm starting to run out of ideas, must be missing something. Do you have BLE sniffer to catch what's happening on air? If you have a nRF51 dongle you can use our sniffer sw here.

Another thing you can try is to connect to your application with Lighblue (third party app) and see if your ipad is able to keep the link for some time to rule out issues with protocol timing,etc.
