MC13213 - modem issue

Spell — Wed, 07 Jan 2009 16:02:28 GMT

I build a custom board using MC13213 for lighting application.
I use a relays for switch on and off the lamp.
Sometimes, after swtich on or off the lamp, the modem stops to work and restart after 4 minutes.
I suppose that problem is caused by an interference with the lamp switching circuit.
Can this delay depends on a software timeout? And is it programmable?
Can I check if the modem stops to work properly by some status registers or something else?
Thank you.

Hi Spell,

if you are using your own written protocol, then please check our the Errata for the IC.

there is a subject about the timer3 that will set the Radio is idle mode and needs to be re-initiated into

receive mode again.

Hi Mads,
I know about this issue but I'm using 802.15.4 MAC/PHY codebase so I think to be ok...
