how to start a "hello world' and connect the board to my mobilephone

[Cong Ma]

I turn on the device, the led turns green. And I use usb to connect it with computer then I  open the nrf connect for desktop, the bluetooth low energy tool,

10:51:05.822

Received status with code 0 PKT_SEND_MAX_RETRIES_REACHED, message: 'No response from device. Tried to send packet 6 times.'

10:51:07.010

serial port COM3 closed.

10:51:07.015

Error occured when opening port. Errorcode: NRF_ERROR_TIMEOUT (0xd)

then this error happened, and I cant find the device on my phone.

How can I start a hello world with my phone?

Hello,

Which board to use with nRF connect. You can find the list of supported boards here: nRF Connect Bluetooth Low Energy

Best regards,

You will have to set up the SDK first to be able to build the sample applications. If you don't have this set up already, you can follow the instructions. here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.0/nrf/getting_started.html#getting-started

Hello, 

I have successfully linked the 5340 to my mobile phone and have successfully used the phone to send messages to the device. But I don't know how to use the device to send a message to the phone. I don't know where I can enter text in the visual code. I tried to type HELLO in the terminal but nothing happened.

And I want to test the power of the 5340, can I use the NRF6707? It looks like only works with the NRF51,52 series.

Many thanks

Cong
