What are AT commands and why are they useful?
AT commands are instructions that control the communication between a device (such as a phone or an ESP8266 module) and a modem (such as a GSM or Wi-Fi module). The name "AT" comes from the prefix that is used to start each command line (for example, AT+CMGS). AT commands can be used to perform various tasks such as sending and receiving SMS, checking network status, setting up a Wi-Fi hotspot, etc.
AT commands are useful because they allow you to communicate with your device in a simple and standardized way, without needing any special software or drivers. You can write your own AT commands or use the predefined ones that are supported by your device or modem. You can also use different programming languages or tools to write and execute AT commands.
How to use Write at Command Station v1.0.4.rar to send and receive SMS using AT commands?
Write at Command Station v1.0.4.rar is a software that allows you to write and execute AT commands in a simple and user-friendly interface. You can download it from here. To use it to send and receive SMS using AT commands, you need to follow these steps:
Connect your device (such as a phone or an ESP8266 module) to your computer via a serial port (such as USB or Bluetooth). Make sure that your device is turned on and has a SIM card with enough credit.
Select the appropriate baud rate, port number, and line termination for your device in the settings menu of Write at Command Station v1.0.4.rar.
Write your own AT commands or use the predefined ones in the software.
Send and receive SMS by using the AT+CMGS and AT+CMGR commands respectively.
The AT+CMGS command allows you to send an SMS message to a specified recipient number. The syntax of this command is:
AT+CMGS=""
The should be in international format (for example, "+1234567890"). The stands for carriage return (enter key) and the stands for end of message (control key + Z key). The should not exceed 160 characters.
The AT+CMGR command allows you to read an SMS message from a specified memory location (index). The syntax of this command is:
AT+CMGR=
The should be a number that corresponds to the memory location where the message is stored (for example, "1"). The stands for carriage return (enter key).
What are some examples of using Write at Command Station v1.0.4.rar to send and receive SMS using AT commands?
To illustrate how to use Write at Command Station v1.0.4.rar to send and receive SMS using AT commands, we will show you three examples of different scenarios:
Example 1: Sending a "Hello, World!" message to a recipient using Python code
In this example, we will use Python code to write and execute the AT+CMGS command that will send a "Hello, World!" message to a recipient number "+1234567890". We will use the PySerial package to communicate with the serial port where our device is connected.
The Python code is:
# Import PySerial package import serial # Define recipient number recipient = "+1234567890" # Define message text message = "Hello, World!" # Create serial object with appropriate settings phone = serial.Serial("/dev/ttyACM0", 460800, timeout=5) # Write AT+CMGS command with recipient number phone.write(b'AT+CMGS="' + recipient.encode() + b'"\r') # Wait for ">" prompt phone.read_until(b">") # Write message text phone.write(message.encode() + b"\r") # Send end of message character phone.write(bytes([26])) # Read response from device response = phone.read_all() # Print response print(response) # Close serial object phone.close()
The output of this code is:
b'\r\nOK\r\n\r\n+CMGS: 26\r\n\r\nOK\r\n'
This means that the message was sent successfully with an index of 26.
Example 2: Receiving an SMS from a sender and displaying it on the screen
In this example, we will use Write at Command Station v1.0.4.rar to read and display an SMS message that we received from a sender number "+9876543210". We will use the AT+CMGR command to read the message from the memory location where it is stored.
The steps are:
Open Write at Command Station v1.0.4.rar and select the appropriate settings for our device.
Wait for a notification that we have received a new message. For example, we might see something like this on the screen:
+CMTI: "SM",1
This means that we have received a new message in the SIM card memory location 1.
Write the AT+CMGR=1 command to read the message from the memory location 1.
Press enter and wait for the response from the device. We might see something like this on the screen:
+CMGR: "REC UNREAD","+9876543210","","21/12/23,01:55:10+32" Hello, this is a test message.
This means that we have read an unread message from the sender number "+9876543210" with the text "Hello, this is a test message." and the timestamp "21/12/23,01:55:10+32".
Example 3: Sending and receiving SMS in different languages and encodings
In this example, we will use Write at Command Station v1.0.4.rar to send and receive SMS messages in different languages and encodings. We will use the AT+CSCS command to set the character set for the device and the AT+CSMP command to set the message format parameters.
The steps are:
Open Write at Command Station v1.0.4.rar and select the appropriate settings for our device.
Write the AT+CSCS="GSM" command to set the character set to GSM 03.38, which supports most European languages.
Press enter and wait for the response from the device. We should see something like this on the screen:
OK
Write the AT+CSMP=17,167,0,0 command to set the message format parameters to text mode, 7-bit encoding, no validity period, and no class.
Press enter and wait for the response from the device. We should see something like this on the screen:
OK
Write the AT+CMGS="+1234567890" command to send an SMS message to a recipient number "+1234567890".
Press enter and wait for the ">" prompt.
Type the message text in a different language, such as "Bonjour, ceci est un message en français." (Hello, this is a message in French).
Press control key + Z key to send the end of message character.
Wait for the response from the device. We should see something like this on the screen:
+CMGS: 28 OK
This means that we have sent a message with an index of 28.
To receive an SMS message in a different language and encoding, we need to set the character set and message format parameters accordingly. For example, if we want to receive an SMS message in Chinese with UCS2 encoding, we need to write these commands:
AT+CSCS="UCS2" OK AT+CSMP=17,167,2,25 OK
The "UCS2" value sets the character set to UCS2, which supports Chinese characters. The "2" value sets the encoding to 16-bit. The "25" value sets the class to 5, which indicates UCS2 encoding.
Wait for a notification that we have received a new message. For example, we might see something like this on the screen:
+CMTI: "SM",2
This means that we have received a new message in the SIM card memory location 2.
Write the AT+CMGR=2 command to read the message from the memory location 2.
Press enter and wait for the response from the device. We might see something like this on the screen:
+CMGR: "REC UNREAD","+861234567890","","21/12/23,02:10:15+32" 004E006900680061006F002C002000E8BF99E698AFE8A681E6B58BE8AFADE4B88DE6B581E3002E
This means that we have read an unread message from the sender number "+861234567890" with a hexadecimal string that represents Chinese characters in UCS2 encoding and the timestamp "21/12/23,02:10:15+32". To decode this string into readable characters, we can use an online tool such as this one. The decoded message is "你好这是一条中文短信" (Hello, this is a Chinese text message.).
