Not able to run ble_app_uart example with iOS nRF Connect app

[sprasad]

Hello,

I'm trying to run the example ble_app_uart using nRF52840PDK and iOS 11.

The device appears as Nordic_UART but when I connect, nothing shows up. The following screen remains. Also LED 1 stops blinking and starts glowing continuously. Where can I be going wrong here?

Hi,

Which SDK and Softdevice are you using? Which phone have you tried with? Have you tried with different iOS devices? When LED1 stops blinking and is just glowing, means that your device is connected/trying to connect. It seems like the apps hangs up, do you disconnect after a while?

Hi,

I tried running the uart example on nRF52840-PDK, and was able to connect with an iPhone 6. Have you modified the example? 

It might be possible that someone else nearby is connecting to your device, but I don't think that is the case here. No, you shouldn't need any specific setting. Try turn off/on bluetooth on your phone, see if that helps.
