nrf52382 firmware program lose

[lulu]

After nrf52382 is written into the firmware program, the test runs OK. After it is placed for a period of time, it is checked again. It is found that it is not running. Use the JLINK tool jflash to read the data. Why is this

How, exactly, do you determine that?

As you have a JLink, have you used it to debug your code & see what's happening?

Have you tried adding UART or RTT output to see what's happening?

etc, etc, ...

Under normal operation, there is broadcast, which can be searched with NRF connect tool. However, the board in question can not be searched.

But that doesn't mean it's not running - just that the advertising is not working, or not being seen.

Again, what debugging have you done to find out what's happening?

Note that most of the Nordic SDK example do stop advertising and go to sleep after a while (a couple of minutes) - by design.

We removed the sleep part

But did you make sure that it re-starts ?

Again, you have a JLink - use it to debug your code !
