Hi! 

I have old code written in nRF51 enviorment with SDK nRF5_SDK_12.0.0. 

I've successfully flashed the softDevice (s130_nrf51_2.0.1_softdevice.hex).

No error occurs when trying to flash my device (an relay).

Everything used to work. Everything I've changed is for how long the relay I suppose to be open (from 1 to 10 seconds). 

Can anywho please help me fix this.

  • Hi Johan

    What do you mean by "how long the relay is supposed to be open"? Is it for how long it is scanning for advertisements? My guess is that this increase causes it to crash with another function, seeing as a relayer often scans for a duration, and then advertises (or relays) what it picked up and sends it to a central. What may happen is that when it is "open" for that much longer, it doesn't have time to do its other tasks before it has to go open again. What is the interval between each "open" period?

    Have you tried debugging it at all, so that you might get an error message or you're able to see where the application hangs?

    Best regards,

    Simon

  • Hi again!

    Yes, I thought that might be the problem. So I changed it back and same problem occurrs. I've tried to debug and cannot see where the application hangs. But, I will have a more experieced colleague looking at it.
