I'm not familiar with what board you're using the nRF52805 module on, but do you know if it includes a LF crystal? If not, that could be why you only saw the device advertising for a brief moment before the application drifted without the correct clock configuration.

Can you try setting the following defines in your project's sdk_config.h header file to these values and flash it onto your nRF52805 (using the Debug Out pin header).

//==========================================================
// <o> NRF_SDH_CLOCK_LF_SRC  - SoftDevice clock source.

#define NRF_SDH_CLOCK_LF_SRC 0
#endif

// <o> NRF_SDH_CLOCK_LF_RC_CTIV - SoftDevice calibration timer interval.

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.

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, im using the example given by nordic periheral uart and with this service I'm using my phone to connect with puty and communicate. I'm giving you the main file.

Just to make sure, your "app" is nRFConnect for Mobile, correct? Can you upload the main file here so I can take a look at it?

Hello, i tried to change the duration but i have a problem now I can't see the device in my app even if I flash the code correctly do you have an explanation? I'm not going to make new tickets and I m going to solve those problems about nrf805 here.

The easiest way to make sure the device doesn't go to sleep while advertising is to set APP_ADV_DURATION to 0 which will let the device advertise indefinitely. The APP_ADV_DURATION is called to set the advertising duration in the advertising_init(); function, and is forwarded to advertising_start(); which will last for that amount of time before moving to the idle_state_handle(); function in the main loop if the device doesn't connect to a central device.

Hello again, no i didn't disconnected the module.Okay, i would like to know how to not be in sleep mode. Where can i found this on the program? Thank you in advance.

I was talking avout the android app because i would like to communicate between my phone and my laptop.

Thank in advance for your help Simonr

[quote user=""]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[/quote]

Have you perhaps disconnected your nRF52805 module from the DK so that it is not powered anymore? Or have it been left on and advertising for so long (more than 3 minutes) that it has gone to sleep mode? If so you need to reset or power cycle it to start advertising again.

Regarding the nRFConnect app, are you talking about the nRFConnect for Android or iOS app or the nRFConnect for Desktop BLE app? Either of them will indeed stop scanning after a set amount of time and you need to start scanning again.

Best regards,

Simon

I have seen another problem : the problem is that my app ( that i took from nordic expire i cant seen the device after some minutes) could someone explain me why??
