The nRF52840 stops working in the multilink example.

Hi,

In the multilink example, we are working on 4 links.
I have 8 devices.

In the test process, if you connect 4 units first and turn off the 4 units connected at the same time, 4 other units try to connect and then they die.

Can a connect packet and a disconnect packet be killed if they are twisted?

Hi Jiwoon,

Which SDK version and Softdevice version are you running on the boards? ( -> nrf 52842 DK?)

Could you send your "sdk_config.h" file? (how many links have you defined?)

I didn't quite get the setup, could you elaborate?

So you have one device that acts as a central and 4 other devices that acts as peripherals, which you then turn off? 

 

Thanks for answering my questions.

hi,

What I am using is SDK15, Softdevice 6.

And the sdk_config.h setting is like this.

8546.sdk_config.h
