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

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

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

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

Now I can send text from phone to the device, but still cannot send text from device. Where should I enter the text in the visual code? I cant enter anything in the COM listener. Maybe it is a stupid question.hahaha

Many thanks

Thank you. Can the nRF6707 power be used on the 5340? I see on the product page it says yes, but in the quick start of the product description it says it is suitable for the nrf51,52 series, which is confusing.

Please follow the "testing" instructions here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.0/nrf/samples/bluetooth/peripheral_uart/README.html#testing

You can use an ammeter or an oscilloscope as well. Please refer to the "Measuring current" section of the DK user guide for more details.

I see nrf-ppk II is out of stock. Can I use nrf-ppk I?

Many thanks

Thank you. I have tried your way and successed! Now I have linked the device with my phone, but I dont know how to send message from the board 5340. This may be a newbie question. 0.0

Many thanks

Please program the peripheral_uart example using the default prj.conf and no additional kconfig fragments.

And hci_uart is not a complete standalone Bluetooth application like peripheral_uart is. Please see the sample description for more details.

Hello. I flash the hci_usb to the nrf5340. Now LEDs 1, 2 and 3, light up, but I still can't find the device on my phone as well as on my computer. And I running the peripheral_UARt is still the same problem as yesterday.

I set the prj_cdc.conj configuration because I use usb to Link the board to the computer. And set the Kcongfig.fragments like this. For code I didnt change anything.

Thanks. So the project is being built with a bootloader. Did you add or change any configurations? The bootloader should not be included if you just build the example as is.

Please post the full log. A screenshot that shows your vs code window may also be helpful.

Thanks. I tried the bluetooth peripheral_uart，but when I build the application this error happened.

FATAL ERROR: command exited with status 1: 'd:\nrfconnect\NRF\toolchains\v2.0.0\opt\bin\cmake.EXE' --build 'd:\nrfconnect\project\peripheral_uart\build'

Does this look like something has gone wrong with CMAKE?

Many thanks

You have to select one of the Blueooth peripheral samples here https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.0/nrf/samples/samples_bl.html if you want to test BLE connectivity with your phone. The blinky sample does not include Bluetooth at all.

okey, now it is working~ but how can I find the device on the phone with the nrf connect for mobile app?

Many thanks

Please try to build and program the blinky sample in /ncs/zephyr/samples/basic/blinky. Alternatively, send me the project you are using now so I can try it here.

Now I have switched to another 5340 board for the BLINKY test and the results are still the same, I think there is something wrong with the SAMPLE code or it does not apply to the 5340

OK thanks. Did you build sample for 'nrf5340dk_nrf5340_cpuapp'?

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

I use the sample just called 'blinky' and the tutorial is on the youtube(141) nRF Connect for VS Code, 4: Flash an application to a board - YouTube

Hello,

Which one the blinky samples did you flash? Also, can you point me to the tutorial you used?
