Can anyone tell me how I can send the following arduino code, in a single SMS message via GSM network
Serial.print("http://maps.google.com/?q=");
latitude();
Serial.print(',');
longitude();

Can I assign a text message sent from my gsm module to a variable in Arduino code?
I have tried to work on sending SMS to gsm module from my mobile phone. I want to write a code to send sms to GSM module and assign the variable to a defined variable in Arduino code. For example sending sms to assign password and ssid for WiFi Manager.
Yes you can. Read more about how to use GSM with Arduino here.
Is it possible for an Arduino Uno subscribe/connect to MQTT Broker (Mosquitto) without using Ethernet Shield or Wifi Shield?
Actually I have a Wifi module (ESP8266) with me, unfortunately it won't allow me to upload sketch and I keep getting error error: espcomm_upload_mem failed
When I interface Arduino Uno with ESP8266 Wifi Module, I construct like this:
And I have included Generic ESP8266 Module in board manager.
Is it possible for an Arduino Uno subscribe/connect to MQTT Broker (Mosquitto) without using Ethernet Shield or Wifi Shield?
Of course you need a network to handled a PubSubClient.h library for your MQTT Broker.
I keep getting error error: espcomm_upload_mem failed
I think you have something wrong about the wired or the code, can you post your schematic and your code into your question? so that i get why have this errors.
see this library.
I am trying to write standalone ESP8266 code so that it can communicate to wifi and change its states. For this, what I want to do is to send some command "AT+CWMODE=1" or "AT+CWMODE=3" to ESP8266 via code and toggle them on push button tap.
So, like in Arduino there is a Serial.write which writes on a serial monitor via SoftwareSerial class.
But when I am sending Serial.write("AT+CWMODE=1") it prints on the monitor as a string rather than changing the wifi state.
Is there a way to send AT commands without using Arduino chip software serial pins?
Thanks.
Sorted out the issue. All those who are new like me to ESP world, I did the serial.write "AT" commands using wifi classes of Esp8266.
You need to connect the board as ESP8266 Generic Module and send/receive data using ESP8266Wifi class, by reading the scanned networks, changing mode, using Serial.read on the connected devices on Access point of Esp8266.
Let me know if someone need help on this future, I will be happy to help.
I am using SIM9000A GSM Modem and have it connected it to my PC.
The issue is that whenever SMS is received by my SIM I receive below data in PC:
+CMTI: "SM",8
I want that all incoming SMS should be directly be read in PC and need not send any further command. Something like when SMS comes - GSM modem should actually send SMS content to serial port.
Below is the output received for CPMS enq.
AT+CPMS=?
+CPMS: ("SM"),("SM"),("SM")
You can use the AT+CNMI command to tell the GSM modem to direct incoming messages directly to the serial port. The full command, with parameters, is: AT+CNMI=2,2,0,0,0
AT+CNMI=2,1,0,0,0 sets the modem back to indication only mode and AT+CNMI=2,0,0,0,0 does not send any indication when a new message is received.
I am sending data continuously to a remote server using the SIM300 GSM/GPRS modem connected to an Arduino Uno. At the same time I want to check if I have received an SMS on the SIM card.
In the setup function I have configured the modem to GPRS mode and executing the AT+CIPSEND continuously to send data in the main loop program. In my interrupt routine I want to check for the SMS notification using the AT+CNMI command. So is it OK to check for SMS notifications while the modem is operating in GPRS mode or is there a clash of SMS and GPRS mode because the interrupt modem is running asynchronously along with the main program?
While I shall not guarantee that this SIM300 modem is without any errors, there should be no problem checking SMS while GPRS traffic is ongoing.
The AT+CNMI command is just a command for reporting new SMS messages arrived on a serial interface, which is a local TE-TA1 issue and independent of network activity (which by the way fully handles sending/receiving SMS messages even when there is ongoing voice or data calls (circuit switched or packet switched)). You have to receive the +CNMI UR codes on a different serial interface than the one which is sending data though.
For more details about AT+CNMI I recommend that you look into the 27.005 specification.
