NRF CONNECT APP AND NRF805

[lm]

Hello, 

I'm working with a NRF52840 DK and a module BLE nrf805.

I'm programming thanks to the software SEGGER.

I have sent the blinky simple in my dev kit to test a simple thing. For about 2 months now, i have been working with the Module BLE 805 because i have to use it for a project. After several times, i followed the tutorial (https://devzone.nordicsemi.com/guides/short-range-guides/b/getting-started/posts/developing-for-the-nrf52805-with-nrf5-sdk) and i used the example that was given because i wanted to send The peripheral UART example (Peripheral UART/Serial Port Emulation over BLE (ble_app_uart)) 

. It worked because with my dk and my module fixed to it. But i remark something that i don't understand : theAPP. (nrf connect app)

The first time that i send my program i saw in my app my module and his correct mac adress. But now i dont know why i cant see the device anymore (even when im trying to resend it)

Did someone has already had this issue?

Is that a problem of stability? 

thanks in advance

Hi

Thank you for the image, that explains what the issue is. The external nRF52805 board should be connected to the DEBUG OUT header (P19). DEBUG IN is dedicated to use an external programmer to program the on-board nRF52840. Please read the Debug Output section in the nRF52840 DK user guide for details.

Best regards,

Simon

Yes, i tried actually with the 2 " Debug in" and" debug out" and i don't why i can send the program (blinky or peripheral uart) but i cant see any type of program in nrf connect application on my phone.

I'm kind of worried because last week it was working i saw the program ( on my nrf52840 and in my 805 ) i was happy because i was finally able to flash the code and see it in the app.

But after a few seconds, i couldnt see the program anymore it desapears on the phone, I told myself its okay im going to change the app duration in my code (main part) but since then impossible to see the flash of the code of the nrf805 (nrf52840 working more or less)

i have the feeling that the fact to send this program is unstable on my nrf805

Do you understand or do you have an explanation?

Thank you in advance

Best regards.
