I built 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 and sometimes never restart, I must reset manually the board. I suppose that problem is caused by an interference with the lamp switching circuit because without lamp this problem doesn't happen. 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, Filippo
