Hello,

I am using 2 LaunchXL CC2640r2f, my code is based on multi_role.

When I upload code to both of them and connect one to the other everything works fine.

When I upload the same code (no changes) to just one of them and try again, they do not connect, I get p_msg->hdr.status == blePending and then GAP_LINK_TERMINATED_EVENT.

I know that uploading code removes all pairing information from that device while the other still has the info, but why can't it connect?

Thanks,

Amit

Hi Amit,

Why are you reloading the code? If you want to restart the application you can use the "reset" button on the LaunchPad.

What changes have to made to the multi_role project?

Thanks,
Elin

Hey Elin,

Reloading the code is not the issue.

The point is, if one of the units has pairing info and the other doesn't, they do not connect. Why is that?

Also, is there a way to delete all pairing info from the code?

Thanks,

Amit

Hi Amit,

Can you please post the sniffer log?

It should be possible to reconnect even if just one device contains the pairing information.

Have you made any modifications to the multi_role project?

Thanks,
Elin
