Pavel,
thanks so much for your help so far. The client is very comfortable with the application. Only thing is that I need to output a LOUD tone on confirmation that the SMS has been successfully sent.

I'm using

play_tone ("SCAN OK", TONE_POSITIVE, DURATION_SEC, DEF_PLAY_DURATION);

but it's not loud enough. How do I get a LOUD confirmation beep?

Thanks for any help you can give.

What phone is it? It really depends on vendor. On some nokias we used TONE_RADIO_NO or TONE_BEEP and it was quite loud. Some phones ignore duration and it's good just to repeat play_tone() several times.

Maybe you could also connect a beeper to some output? Then you can make really huge noise.

[rhamel]

If I solder the beeper which has 2 wires, one wire to P6 and the other to GND, will that work?

Can you point me to some sample code to turn it on and off, please?

Thanks in advance,

Richard

You will connect beeper between VCC and some port Px. You need 3v beeper, e.g. kpe212 23x16mm. When you set Px to zero it will beep.

You could also use something bigger with external power and use one of the opto isolated outputs to turn it on.

As for code - I would recommend to install pager application for testing. All code is there. Or you can find it in autoalarm.c

You need to:
1. select what port/output to use
2. in your code set it to be output - only once during init
3. set it 0/1

In autoalarm.c look for e.g. ALARM_OUT_BLOCK or ALARM_OUT_AIRCON (not the _EVO_ ports, these are for opto isolated outputs).

I soldered an LED into the VCC and P4. The client gave me a LED to test it with. I hope it doesn't make a difference using a LED instead of a buzzer.

When I scan, I use a multimeter to test the voltage between the LED and each of the holes P1 -> P13.
I notice a 2.97 volt difference between P9 after I scan, but 0.0 volt before I scan. Is this significant? Why is P9 responding? Shouldn't it be P4?

My code looks like

Ok, I soldered the LED to VCC and P9. Now, it turns on just as I need it.

Thanks so much for your help, Pavel.

Pavel,

The client is concerned that someone may accidentally or deliberately disconnect the charger from the phone.

Since our app polls continuously, the charger is essential.

How can we know if the charger becomes disconnected from the phone?

Does the phone communicate this to the Turbo board?
Do you have sample code that detects a disconnected charger?

He wants the board to send an SMS if the charger is disconnected.

Please advise. Thanks.

Richard

Unfortunately there is no such info from phone but you could monitor the charger on one of the inputs, i.e. no voltage -> no chrager -> report.

[rhamel]

Pavel,
to which of the inputs should I connect the charger?

I noticed in turbo_lite_2-r01050902.pdf, on page 4 of 6, the warning
"Imax of one port is 10mA, overall current should not higher tham 50mA - limitation depends on mobile phone used."

This concerns me because the charger outputs 5.7V @ 800mA. I don't have any charger which outputs less that 3.7V @ 340mA, which still seems to be too high according to the warning.

My knowledge of electronics is non-existent (I'm just a programmer), so do I need to use some kind of resistor between the charger and the Turbo Lite 2 board?

I was thinking of connecting one wire from the charger to P8 and the other to GND on the board. Is this the correct thing to do? I'm very nervous of burning out the board.

Also, if I do connect the wires to P8 and GND, do you have any sample code you can point me at, which will allow me to monitor the current coming in to the board? Which will allow me to send an SMS when the current fails?

I already know how to send the SMS, but I am not sure how to monitor the current.

Thanks for your support,
Richard

Use the opto isolated input, you have 2 of them. Look into Pager v2 datasheet for details. You can connect it directly - in the worst case you will damage the optocoupler but you have two You might to use 1k resistor but shouldn't be neccessary.

The 10mA warning is for P1-P13, which go directly to mcu, no protection.

As for sample code - use the pager-210 source, all is there. You may try this application first to test/read the value. The code is also in AA application.

Pavel, I have a problem loading apps using the programmer.

Earlier this morning, I WAS able to load two apps, but now it does not load.

When I run prog_apps, I get the output :-

I have tried it with a different SIM but had the same response.
I can upload and remove modules to/from the programmer without any problem.

Can you help me, please? Thanks.

Belay that last post.

All of a sudden the friggin' thing starts working again! This is not good for my blood pressure.

[pz]

Good it recovered before I could answer. My recommendation would be to reflash TM2 kernel. But maybe it's some wrong contact?
