Troubleshoot nRF52 to iOS connectivity

Our hardware based on Nordic’s nRF52810 communicates with an iOS app to send/receive data which is being displayed on the hardware‘s display. While core-Features work we face issues with connection stability while communicating with an iOS device. We require an expert who is very experienced with nrf52 communicating with an iOS device under low-power requirements in order to debug and improve the connectivity part. Firmware is developed using Segger and nordics nRF52-DK development kit. We need someone who has a modern iPhone (>iPhone X) in order to debug the setup
