flashing an Ezurio BT510 sensor using the nRF52 DK

[Kilsally]

Hi,

Apologies for a newbie question (I am far from a developer and just need to flash firmware)

I have a nRF52 DK connected to my PC running nRF Connect for desktop

Should the sensor appear on the list of devices in nRF Connect when I had the debug out cable connected to the sensor?

I need to flash a hex file to the Ezurio BT510 sensor

Yes, windows command prompt. In termnal window in nRF connect you have to selec device. Large blue section that says "Select device" in your screen shot. It shot drop down and show the DK you have connected. Select the one and then you can connect to port.

Best regards

Asbjørn

Hi - I don't get any response with com 3 or com 4 (no others showing)

Hi - if I use cmd instead I get the following

Are you looking for UARTs? There are no UART pins on the SWD connector you are connected to in the picture so that won't work. That connector is debugging and programming only. For data transfer you can look at RTT, one of the logging backends in our SDKs

Hi - I am looking to flash custom firmware that I have been provided with onto the Ezurio BT510 sensor

Then you should use the programmer app, not the terminal app. The programmer app uses the SWD interface to program while the terminal app tries to connect through the UART lines on the debugger and they are connected to the nRF device on the DK itself.

Hi - thanks, this is what I was originally doing but with the debugger cable

It looks like I may have been advised wrong at this side re cables etc.

So to confirm I should be connecting to here?

That will be the same as using the 10 pin header, you will be able to program the board but there will be no UART connection. That means the programmer app will work while the terminal will not.
