sms to control pic..pls help...

[f_lez]

I'm using rb6 and 7 connected direct to phone, and a gnd.

its not a pretty sight to look at is my 'development stage' but I am moving to a better pcb!



It has 3 cables..........

one is a usb data cable, I'm using that as an input to the pc on com5 to monitor what the phone is sending to the pic.

Other cable is a serial data cable on com1, I'm using that to monitor what the pic sends to the phone.

Phone is connected to pic and the cables above, but it does not need the cables to the pc, just for debugging.

I used no resistors between phone and pic, but I think I should have done, say 560 ohm at a guess as a bit of protection as phone is 3v not 5v, but after weeks of running it like this, nothing has gone wrong.

I use power from usb for the pic 5v.

the max 232 part ...is it necessary that the DB9 pin 4 and 6 shorted .7 and 8 shorted together which is shown in http://pinouts.ru/CellularPhonesCabl...e_pinout.shtml
does it serve any purpose?

ericsson only pdu mode, no text mode,

pdu is not that hard if you only look for 'key' strings of digits.

download ericsson manual, at+cmgr=1 only read memeory 1, of the current memory, you need to change the current memory from sim to phone (SM to ME)

I connected t610 (and t68i) to pic 16f88, no max232, no resistors, just wire.
