Help mga master...Connecting GSM module to the PIC(Pic16f628A)

[rayleigh]

I having a problem po...kasi ung binigay saking documentation about sa GSM(egizmo) iba dun sa binigay nilang GSM module.. 44 pins po ung sinasabi sa documentaion and then 28 pins lng sa gsm na binigay nila.
ung nid po diba na iconnect sa PIC ay ung RXD and TXD pero wala po ako makitang ganun sa pin nakalagay lng RXD2 and TXD2 sabi sa documentation for software debug...

Question po:
1) pede po ba un ang gamitin ko ung UART2 (RXD2 and TXD2)?

2)Could you teach me how to connect it to the PIC...pls master!!.. gagamitin ko lng ung GSM sa security alarm if  nakadetect sya ng signal from sensor mag sesend lng msg sa user.

3)meron po ba kayu alam na instruction para mapag aralan ko po ung pag proprogram sa PIC about sa UART how to communicate to GSM module.

A BIG THANKS PO SA MGA MASTERS ^^

I have some pictures of GSM module

see this one


you have to set SW1 accordinglly 

[marcelino]

natest mo na ba sa PC yang modem mo using hyperterminal?

were you able to send and received sms?

alam mo na ba kung papano mag compose ng message using hyperterminal?

gawin mo na muna yan... then balik ka dito.

Note how the strings that are being replied by you modem to hyperterminal. importante yan.

BTW, what language are you going to use programming you GSM modem?

[waterbender]

Your reading the wrong manual, para sa GSM/GPRS module ung binabasa mo yan kasi un ung 44 pin. Your module is the GSM only type (the 28 pin), check here: http://www.e-gizmo.com/KIT/MODEM.HTM

Just click the GSM modem technical manual. Ang bilis ni sis c0oLėt mag post..

so true. sana may funding galing sa school para sa mga high priced materials like that.

master of GSM

laging ready yung popost.. hirap unahan=)


actually medjo nakakatamad na rin magreply sa ganitong thread.. paulet ulet.. daming related topics oh=)

saan nakakabili ng Simcard holder wala akong mahanap

sana gumawa si master coolet ng gsm applications thru microcontroller tutorial para basahin na lang ng mga members.. like me..

sa e-gizmo meron yan. sa connectors.

i was thinking the same thing...

sis coolet, kung may e-gizmo gsm modem ka, paggawa naman... post mo schematic. then gawa ka ng simple interfacing program using BASIC.
i will take care of CCS C (or hitech kung kayanin ng powers) equivalent program. kokonvert ko based sa gawa mo

[Kaizer03]

uo nga.. hehe

gusto ko malaman eh kung paano iextract yung messages... EG

CHECK STATUS
IF ON
OFF
ELSE
ON

parang ganyan.. line by line eextract yung message or by space.. hehehe wala pa kasi yung gsm module ko kaya nitatamad pa ko mag-aral nitong mga AT-Commands..

parsing ba ung minemean mo master kaizer?

owkie.. gawa tayo bagong thread... titol of thread any suggestions

@waterbender

yap.. the condition is sa newline or sa space=) sana dumating na sa sunday yung module para di na ko magtanong

dagdagan na lang din ng "with practical example using BASIC" haha.

@kaizer: ow.. sis paturo ako ha.

thanks po sa help... pagaaralan ko po ung hyperterminal commands para sa GSM...BTW mikrobasic po ung gagamitin ko pang program ng PIC. balik po ako ulit pag ok nako sa hyperterminal.

thanks po master:

mga master ok napo ako sa hyperterminal nakakapag send at read msg napo ako using PC. alam ko na din po ung connection ng GSM to PIC. now mag tatry napo ako mag program sa PIC..

Question po:
1) meron po ba kayo sample program ng GSM sa PIC- Im using Mikrobasic, bale ang gagawin lng nung gsm pag may narecieve na signal from the sensor mag sesend cya ng message to 2 person.

thanks po again!
