[smithpl]

Hi,
I have a problems with SMS module.
I did upgrade to newest version of firmware but it not resolve problems.

I have a full acces to SMS module by PC software.
Module not sending SMS. red LED blinking 1sek but some times
Yellow led blinking... I dont know how :-) this is sequence first several times (8-12) very fast, next 2 times, nex 1 long
afterd that Power LED is switched off, after that Power LED is going on, red blinki and again yellow.

When I plug off power supply SMS module is working ( so I think the battery is OK )
I've changed 2 SIM cards from differents operators

Any helps?

You have noticed that the power LED shortly go out in your video?

So it seems the Battery is weak.
The result is: during the SMS module trying to connect to the GSM network (higher current) the power drops off => the SMS module restarts.

OK, I'll replace battery and will check again :-)
( I think it's a problem, the battery has still 3,3V and not increase value )

I'ce replaced battery and I had to replace battery driver because it was demaged. Now sms module works well :-)
