Hi, I am using an Arduino Uno with the official GSM shield. The sketch below will enable the Arduino to communicate with the SIM800L module over the serial monitor. my question is if I use AT commands on the code and upload them, for example: Serial. i have 2 HC-05 module and i already set one to a master, and another one to slave. Good day to everyone. char* Hi, i am developing a project that send data from sensor to web server through SIM800l GSM/GPRS module. These AT or Hayes commands are a set of commands not only used by the ESP8266 but also by other modems like GSM, Bluetooth, and GPRS. Through this AT command host devices such as Arduino or other microcontroller can communicate with the module. h> #include <SoftwareSerial. So i have an arduino nano and a LoNet 800l but they dont seem to want to talk to each other. At the bottom of the SERIAL monitor ensure that “Both NL & CR” is selected. Hi I am using Arduino UNO with a shield for AT commands. One way around this is to use another character to represent (char)26, say carat, and then instead of blindly relaying input to output you need to read the input, if carat send (char)26 and if not simply relay it on. vodafone. The HC-05 is connected directly to the RX0-TX0 pins. begin(9600); while(!Serial){} Serial Monitor of the Arduino can be used to feed AT commands to the module. 3V and adapt the serial communication to be at The issue is definitely not the with AT commands and I can say this because whenever I send these commands manually from the serial monitor it works completely fine. Arduino Forum 'ERROR' responce for AT commands from A7672. SRJ September 17, 2023, 10:17am 1 iam using arduino uno and AE gsm modem sim900a iam connected GSM Tx –> Arduino pin 9 and GSM Rx –> Arduino pin 10 and iam used SoftwareSerial Library and i have tried a program for sending and receiving sms code that i used is given Programming Questions. 6: 3127: May 5, 2021 Serial Monitor - Weird Symbol HM 10 BLE Module not responding to AT commands. println("AT+CGPADDR); AT+CIMI will return something like: 222107701772423 OK AT+CGSN=2 will return something Hello, I'm working on project using Uno Rev3 and gprs shield SIM900. Yesterday all of a sudden it worked with scenario #2, the AT commands directly without the library. I'm using the Arduino Mega board with GE910-QUAD(GSM Module-TELIT). 2k? resistor; 1 x 10k? resistor; Jumper wires ; First, to set the Arduino board as an ESP programmer, connect the RESET pin to GROUND. It is designed for more advanced users. How can I store the response from my AT commands as a Variable? I've 3 AT commands, for which I would like to store the response in a single variable. My current set-up involves Hello Everyone! I am trying to get to HC-05 to interface with each other on different Arduinos(same exact model) and none of them are not responding to any of the commands like "AT". It is code in the sense that was quoted as code Hello Folks I'm using the Arduino Uno board with GSM Module (SIM 900). 9600 if not power off the SIM, power it back on and try autobauding using the arduino code magnusgsm February 13, 2023, 9:54am Arduino Serial Output. So what is wrong with my Arduino code (the first one) where I send AT commands to BT but nothing happens. MTC C2 cell modem by Multitech. If not he send me an SMS with all data. For what I have read from the forum, the Tx and Rx pins are for the usb, so: -With the wemos I tried to connect the D3 and D4 pins as Rx and Tx. println() after it. h> I was having problems with a my arduino code and the guys on my last thread really helped me out, but now it seens like some hardware issue! My objective here is to send that data of temp/humi to a channel on thingspeak. Also yes I put it in AT command mode. just connected ESP8266 USB to the laptop and started sending AT commands. I have teltonika e12 gsm modem. first, I have a function called "connection_check()"; then, I do this: GPRS_Serial. This video will get you some knowledge on basic AT commands in GSM modem and we will test all the basic necessary AT commands using TT actually I found that it's not related to Arduino code. pt\""); will the arduino execute them without a PC connected with the serial monitor opened? In my program, I need to send 5 different AT commands, then check if the connection is fine. Hi, i'm doing a project with Arduino uno and Sim808 v3. h> Can anyone suggest a good library which I can use for the AT commands to communicate with a 3G Modem ? Arduino Forum AT Commands. begin(FIREBASE_HOST, FIREBASE_AUTH); I would like to have Arduino UNO to send AT commands to the ESP8266 E01 and in that way connect to Firebase and exchange data. Or, post ALL of your code. My problem is i'm trying to do POST requests with AT commands using the Arduino serial monitor ( yes using NL and CR ) I have my backend that is running on my Ec2 instance waiting for client requests. But rather than programming it for a certain tasks can it be used like an out of the box Cell modem? I have played with one particular cell modem a bit. I send RED_ON, and The serial monitor has options to append newline and carriage return characters to each input line you enter - if you select the 'no line ending' option it should behave similarly to hyperterminal.
