Has anyone tried the SMSTimer TAP with a TF5800? Did the TAP at least start properly, i.e. did it print either "Device disconnected" or "Device xxx connected" on the TV screen upon start-up?

At least on one TF5800 the TAP won't even start for some reason, but it has been proven to work on TF5000 and TF5100, so I'd like to know if this is a device/firmware-specific problem or something else...

It was on a TF5800 that I tried it, as described earlier in this thread. It did appear to start OK, but came back with the "echo off failed" and "device disconnected" error messages. This was with a Sony Ericsson T68i and a T610.

I haven't tried it with the newest firmware, but I don't expect that to make any difference.

Did you manage to try it with a Sony Ericsson phone?

Unfortunately I haven't been able to get my hands on a T68i or a T610, but I am still trying to find one. Here in Finland everyone seems to have an old Nokia phone, but there are not too many SonyEricssons out there...

I could borrow you a T630 to debug this problem if you like.

However I have done extensive work with mobile phones

The older Nokias does indeed work fine using raw AT commands if you have the correct cable.

On some phones the AT command parser doesn't start up immidiately ofter the port is opened, so the following algorithm is highly recommended:

Open port

loop:
Send "AT"
Wait 100 ms
if ( there is "OK" in the inbuffer ) {
done!
} else {
wait 250ms
goto loop
}

repeat this for a maximum of 10 seconds.

Cheers, Tommy(?) for the info! I'll have to give that a go this week. So far I haven't been successful in connecting to the Nokia phones, no matter what I've tried...

Do you happen to have any information on which of the serial port lines (or pins or whatever they are) should be up and which down? RTS, CTS etc? Or should the default setup in the Toppy work just fine? It seems it is not possible to control these lines in the Toppy without some serious firmware hacking and I wouldn't want to go there.

And finally, thanks for offering your T630 for debugging. I'll figure this Nokia business out first, I'll let you know later if I'll still need the Ericsson.

And while I am at it, read/send SMS AT commands is a black art... Nokia especially doesn't follow the ETSI standard 100% (it even differs between models) so on several previous projects I had to build up a database of handsets and in what way they differed from the standard.

Have you had some time to look at this? I don't want to buy a Siemens phone + cable when I have a perfectly fine SE T630 in my drawer

No, but you know you can set timers via this web site, if you like? We have an SMS option, though it's not free. http://www.toppy.org.uk/timers/

Am I right in thinking that this relies on having the Toppy permanently connected to a switched-on PC/Mac?

Cheers
