GSM-SMS Using Microcontroller

[zer0w1ng]

True. And currently, I am making an SMS controller using the bt module as the modem using PIC MCU (PIC16F648).
I will release the source code and the simulation files as soon as its finished.

aside sa presyo, ano pa kaya? nagtataka kasi ako, bakit hanggang ngayon, mahal pa din ang modem, whereas, wala ngang interfaces like LCD and keypad  hehehe tapos, tulad din ng mobile phone, maari din namang iinterface sa MCU(or the like).

baka kaya mahal yan e pwde rin sa MMS at GPRS

its tempting to go to that path, but my project, if implemented, will be installed on plantation fields. I suppose a simple rs232 interfacing will be better. But i love that feature of the bluetooth. Sir, can the bluetooth module hack over phones for SMS (assuming bluetooth of phones are turned-on)?

Yes. But needs a little social engineering.

Example: you could rename the module's name to "Enter 1234".
So when it connects, the phone asks for a passkey/pincode, the user sees the bt name and enters 1234.
Which is the modules pincode.  Then the security is bypassed.

so sir, if you good with social engineering, perhaps you'll have an unlimited SMS through your computer... hehehe

I see that the idea is similar to the data cables for mobile phones but though bt. The module will be helpful when you are a heavy texter...
Could that module also facilitates the firmware upgrades for some BT phones? 

OT!!! hehehe

[zer0w1ng]

Phone firmware upgrade via BT is not possible.  The phone's firmware is off at the time and no bluetooth comms.  Only the bootloader will be present.

BTW, this is a short video on using BTSerial1 on a terminal searching and connecting to a bluetooth phone.
Then retrieves all SMS messages.

This is the finished and working sms controller.  I'm planning to build another one using my own pcb design to fit a particular enclosure.  Now that master zerowing has posted his code for the btserial module, I can code scavenge and begin to work on a pic version (if I have time this coming christmas vacation).

wow!!!
nice...
buti ka pa...

[colot]

kakaingget naman poh,...

3315 pa gamit na cp,.

ako 6210 nga lang hirap pa eh, sa 3315 pa kaa.hehe

['yus]

ako, hanggang HW& SW version lang ang kaya sa 3310.. hehe

[marcelino]

ako nga... napaiyak na!!!

Helo mga kabayan... unang liham ko 

Sa wari ko ay iisa lang ang pinanggalingan ng mga kumakalat na sms controlled gadget. Kung hindi ako nagkakamali Smart Car Buddy ang title ng article. Dati nakapost ang source code. Take note basic language ang ginamit. Tapos nabili ata ang code kaya nawala sa net. Pero sigurado ako maraming naka-download ng source code kasi halos magkakamukha ang mga code na lumalabas sa net. Gamit nya don ay DLR3 from atrox at transistor lang ang level converter. Ito ang link.... http://users.picbasic.org/projects/SCBuddy/SmartCarBuddy.htm . Sinubukan ko din i-email ang author and to my surprise sumagot sya at nagbigay ng tip.

I will try to port this 1 with Z8 Encore. Since I already have the hardware.

ok lang yan... marami na din naman nakakaalam!

ang galing nga ng atrox at kahit matagal nangdyan pa din.

[Co0LëT♥]

oo nga maraming natulungan ang Atrox, nagawa ko ang Dlr3 ng walang problema. Ang try ko ngayon ay Mbus naman to replace the 16F84 to 12F675 8 pin DIL package and can run in internal 4 Mhz oscillator so d na kelangan ng crystal... sa palagay ko madali lang kc wala namang secret na itinago sa atrox. I got already the pic, cguro within a week umpisahan ko na ang project pag natapos ko na ang pcb. One question lang sa mga guru's ng forum... ang MBUS at FBUS frame ba ng phone ay string character o Hex format na kaagad. Sa AT kc string character ang narereceive ng micro.

more than 10 years ko na gamit yung dlr3 and 6210, so far wala naman problem except kung nag-hang yung fon. meron ako hex codes to reset the 6210 by sending it by burst kung ayaw na talaga mag-respond yung unit. for now mas preferred ko yung mga gsm modules kasi mas rugged (power on then off lang reset na) unlike sa ordinary fon pag nag-fail ang display ang hirap na gamitin.

uy, thanks sa idea. di ko to naanticipate sa design ko ah... dapat pala may routine sa controller na kapag none responsive na yung gsm module, dapat magsend na ng reset command. pwede naman kasi soft reset (at command ) or hardware reset.

pogi point for you!:)

[defcon1]

here are hex codes to reset the n6210 fon, send it in serial 9800 baud, make sure you dont send any more code after the last hex code

1E 00 0C 40 00 06 00 01 64 03 01 42 77 06

enjoy!

[marcelino]

^i am using gsm modem though...

pero magiging helpful yan sa mga dlr3 - n6210 user.

[defcon1]

one typical routine na ginawa ko is, i send a hung-up command "ATH" sa unit. its very helpful kasi if you want to test the fon if it is still communicating with the controller; you just simply call the unit, kung nag hung-up in less than 10 rings,  it is assumed that it is working normally
