CC2530 Watchdog problem with SE.

Other Parts Discussed in Thread: CC2530

Hello,

I work on a SE network with an ESP as coordinator and an end_device as Simple_Metering.

I try to use the watchdog of the CC2530 (Zstack 2.3.0 & 2.3.1). It works with HA profile, and when I start it only

after association step. When I use all security of SE profile (SECURE, TC_LINK_KEY, KEY_ESTABLISH,

certificates), and that watchdog is starting at begining I can never associat my end_device because it reset

each time before KEY_ESTABLISH_INDICATION.

Thanks,

Launix.

    Hi,

    The problem is fixed with TI help. When end_device is in KEY_ESTABLISH process, we need to send

    callback to Certicom library while processing keys, to restart watchdog (yielding function).
