Kasamiko,

thanks for sharing your project.
I built it according to your above schema but the test I did had no success.
The pics receive 2.8 V. from the phone, is that enough ?
IC2 has your software with my data (phone nr. + text)
IC1 has the the software found at http://www.atrox.at/datacable/dlr3/dlr1.hex
LED1 is always flashing
LED2 is just flashing once.
Could you pls. tell me the pic config (osc, wdt, pwrt) ?
What's the purpose of diode zener (D5 2.7) ?
Thanks your or anyone else support.

Lotondo
