cannot open port with nrf connect

[Ashish]

hi everyone, I've downloaded s140 and trying to run BLE notification example. I'm able to see state changes in the advertising on putty terminal at COM 7, but when I try to connect port using nRF Connect, it always display same message :

Would you like to program development kit on COM 7 with required firmware ?

It selected it OK, the program on chip stops working. Again repeating the procedure lands me into same results?

you need to connect nrf52 or 52 dk board through the USB and select the com port so that PC connected board will work as central and it will search for peripheral devices.

Hi Ashish!

It wont work to connect the same board that has your notification example on it. You need to connect an additional nRF5 DK to your computer with USB, program the development kit with the required firmware, and then use that to scan for your peripheral with the notification example.

You can read more about nRF Connect Bluetooth low energy in the infocenter.
These sections would be of special interest of how to connect a device, scan and establish a connection:
Establishing serial port connection to a local device
Establishing Bluetooth low energy connections

Hope that clears things up. Let me know if you have any questions.
Best regards,
Joakim.

Hi !

I've read the tutorials, I tried to run simple ble_app_blinky example. It works perfectly with Android app nrf_blinky , but when I tried to test it using nRF_Connect, I'm getting same issue with connecting port.

Thanks for your reply. I'm having only one 52 dk board presently. I've ordered one more and I'll test as soon as I receive the board.

Yes, as I said: To be able to scan the device in nRF Connect for windows, you will need x2 nRF5x DK. One that is connected to the computer with a serial port connection to nRF Connect, and one to hold the ble_app_blinky example. Then you use the device with a serial port connection to nRF Connect to scan for the ble_app_blinky device.
Best regards.
