We have successfully tested the nRF52832 HRM and proximity examples with iphone APP (nRF Toolbox & LightBlue). However, when we tested with UART peripheral example (..SDK\examples\ble_peripheral\ble_app_uart), we are not able to make the connection (timeout) from the Iphone.
We have tested with follows: Board: PCA10040 Devices: iphone 6 and 6S, IOS Apps: nRF Toolbox UART, nRF UART, LightBlue SDKs: SDK14, SDK13, SDK11, SDK10, SDK9, Softdevices: S132 5.0, 4.0, 2.0
But it works well with android phone (nRF Toolbox UART). Any suggestion and help?
