is this board supported by lattlepanda alpha?

Something I noticed the hard way: 5V on the "Arduino connector" is not connected to USB 5V (or any other way of actually powering the SIM7600). So if you are powering your "Arduino" from USB note that this shield does not get powered via the 5V rail. You need to either give it USB power separately or use Vin (7V+) to power both this module and the "Arduino"

Though there is a slight upside to this, if your "Arduino" is not 5V tolerant for IO you can put 3.3V on the "5V" rail (also hard-wired to IOREF pin on the header) and have 3.3V IO.

Hello friends, could you please help me... I need to communicate the SIM7600 CE-T module with the Arduino Mega, but I have not been able to do it. Use the information left here to do tests and I have not been able to do it... Can you tell me how I should connect it please? or some diagram that can help me

Hello, i bought this shield a little while ago. i've been testing it and everything works correctly. however, i have a question: if i have this shield connected to 5V, but the electricity fails for a few minutes, is it possible to restart it automatically without having to go there and click on the boot button? thanks. edit: other question, in at+gpsinfo, the speed values is in kilometres per hour, metres per second, miles per hour or nautical knots? thanks again.

Are you able to test with a different carrier's SIM card? It is possible that your current carrier's card does not support the TEL0124 band.

Hi, my MCU (Metro M4 Airlift) uses logic level 3V3. Can I run your module with 5V supplied via VIN but output 3V3 on GPIOs (I need the RI interrupt for SMS notification on the Metro)? Thank you!

Hello there,
You can find the arduino tutorial on our wiki.

What is the maximum current draw on the 5v power input?

Hi,Can you please confirm the on board connector type for the GSM antenna. Looks like uFL ?
Cheers

It's designed specifically for Arduino controllers, so we didn't test it against the Raspberry Pi.
However, since it works on the principle of communicating with the Arduino through the serial port, we think you can connect the D7/D8 to the Raspberry Pi's serial port and write your own code. Of course, you will need to power this shield with 5V via USB.
But sorry we didn't do that, so we don't have an example for your reference.

We are sorry that this shield could not support MMS.

solved

-The chips default buad rate is too fast and needs to be set to a lower rate by setting the Arduino to 115200, then setting the chip to a rate such as 19200, then setting the Arduino's boad rate to 19200. Use following code for the fix.

GSM.begin(115200); // for GSM shield

GSM.print("AT+IPR=19200\r");

//for SIM7600
Serial.begin(19200);
GSM.begin(19200);

My led indicator for power is red. What does this mean?

Hi, can you check if this works with telcel band? because telcel band is 3G B2/1900mhz, B5/850mhz and 4GB4/1700/2100mhz

Hi Tuan,

Please check the frequency bands in the specification and confirm with the FAE of your SIM card operator.

Does this work with lattapanda computers?

Thanks for the help. I've sorted things. I am a beginner :) On Arduino Mega there's 3 additional hardware serials. Hardware serials work MUCH better than software serials. Also, in Sweden this card works, at least for my carrier 3 (TRE).

Can i control an 4g fpv rc car via this board?

Hai whenever I try to get GPS info but I'm getting output like this +CGPSINFO: ,,,,,,,, is there any particular reason for this?

Are there any tutorials or starting code for posting data on web servers?

Hi, i bought the unit. But seems no support for SSL. Can advise new firmware for SSL support.
