Hi guys
I am struggling to get the following info.
I want when I send a SMS to the device to get the following info
Speed in kmh and readable gps location.(link to Google maps)

Also that the devices reads the phone number that has send the sms and if it's not a "linked" number to not send nothing, something like
If(sms 1 received and phone n xxddd)
Do this and that
Clear and memory
Else
(Nothing)
Clear sms memory

Thank you guys

What devices do you have ?
Arduino ?
GPS ?
GPRS ?

Can you read from the GPS ?
Can you send a text ?

It's this device #Aliexpress € 1,52 7%OFF | New SIM800L GPRS GSM Module w/ PCB Antenna SIM Board Quad band for Arduino
https://a.aliexpress.com/_UbnB5

It does send receive SMS.
Board is Arduino nano
GPRS, have used a posted code to control a led via sms

and the GPS ?

GPS module? Have ordered this one on the way
#Aliexpress € 1,06 | ! GY-NEO6MV2 new NEO-6M GPS Module NEO6MV2 with Flight Control EEPROM MWC APM2.5 large antenna for

Can't I get GPS location via the sin card module? Gprs?

By definition, no

They are posts that you can get location using the sim800l module...but not clear for me

You may be able to get a rough position but not the 'GPS' position which, by definition, is only available from a GPS receiver

Ahhh I see, every day something ner is learned. With the module that is on the way I guess it's possible

With the module that is on the way I guess it's possible

I would certainly hope so. A Global Positioning System module that could not give you its position would be a bit useless, don't you think ?

hi guys im back
im still waiting for the gps module...
i am testing some coding but have these problems

-how do i set the pin code to the sim800l (at+cpin"xxxx" ? ) wat the void setup? just with this works or is there something missing?

-How do i respond to a received concrete sms ? if i receive for example, on, performs an action with the arduino and sends me a sms that it is done BUT to any number to sends this message to the device, so i need to be able to id the sender and use this as the number to respond to, the current code i am testing a published one but not much results there
