Hi Bjørn

Just submitted issues on https://github.com/NordicPlayground/iOS-Image-Transfer-Demo/issues/1

And can you reassign this case to Nordic iOS developer?

Thanks

The iOS developer is not a part of the Tech Support team, but I have made him aware of the issue.

Thanks Bjørn

But the iPhone X issues seem critical I can't based on current performance to propose the video stream solution to my boss.

Can Nordic arrange more resource to investigate?

The Mobile applications are maintained by the developers through the GitHub repos.

What is the purpose for adding the print statement at that particular line number?

It would help if you could  perform a sniffer trace using our nRF Sniffer v2. Seein the actual on air packets we can figure out why the disconnection occurs.

The print statement is output the log for show the received data size and base on the log we know the data is not complete.

Can the nRF Sniffer v2. work with nrf52 DK ?

Slow down the SPI to "NRF_SPIM_FREQ_125K" to holding the BLE communication back can make the iPhone X receive data complete sometime but this solution still not stable.

iPhone X seem limited BLE 5 data transfer speed. 

Torbjørn have inital the github commit https://github.com/NordicPlayground/iOS-Image-Transfer-Demo/commits?author=mostafaberg 

Can I contact Torbjørn via devzone.nordicsemi.com? 

Thanks
