Mobile polling

Hi,

I want to make a circuit that tells me what is the signal strength that a mobile is receiving, but the mobile will be placed at another location no near a pc (stand alone).

ie. I want to know the signal strength that the mobile is receiving from a remotely place. I thinked about something of sending an sms with a mobile to this mobile placed at another place and sends me back the signal strength that is receiving.

Re: Mobile polling

You have to read your AT command manual for your gsm module you intend to use. It should list the available commands for reporting signal quality...on Siemens MC45 for example it is AT+CSQ...

Re: Mobile polling

Yes I know but the mobile will not be connected to a pc. it will be placed in a place where i think i have some signal problems. I want to make some circuit that includes a microcontroller that sends a command to the mobile in this case an at+csq to retrieve the signal strength then it stores in it then it tell the mobile to send this information through an sms.

it is possible ?

Re: Mobile polling

ronald,

if you are using a Siemens mobile phone you can search my posts and will find how to send and receive SMS using this phone and an 8051 or PIC.

best regards

Re: Mobile polling

Are you able to write software in C for a PIC?

If you can not do it, I can not help you because this will need a lot of time which i do not have ...

Re: Mobile polling

The only circuit you need is a microcontroller (with all the components it needs to run (cristal, capacitors, power, ...)
Connect the uart to the GSM and write software to receive SMS, get Signal Strength and send SMS (all using AT commands)

Re: Mobile polling

Hi guys,

I made a little thing called "GSM Kontroler", it receives SMS, turns a device (1..6) on or off depending on the SMS, and then returnes an SMS "Turned ON" or "Turned OFF" :)

All that in MPASM for PIC16F84A, for Siemens phones (S25 in my case) with AT commands, serial communication on 19200 bauds.

Did anyone try doing this or sending a simple AT commands to Nokia phones over MBUS or FBUS... I don't know which one.. ???

Look here:
