I'm trying to send a SMS using AT commands and after typing the cellphone number it show the CMS: ERROR 302.
What I'm doing:
AT
OK
AT+CMGF=1
OK
AT+CMGS="<3 digit local area code><7 digit cellphone number>"<Enter>
+CMS: ERROR 302
I've found this post: AT+CMGS returns ERROR but couldn't find a solution. Am I typing something wrong? I've changed SMS-encoding to GMS as the post describes.
Try this:
AT
AT+CMGF=1
AT+CSCA="sms tel. service",145
AT+CMGS="tel. number"
text message here
^Z
Some modems need set CSCA (SMS Service Center Address) always.
And look here for a examples and descriptions.
I found out that sending exactly the same AT commands by hand worked, but sending them from a controller did not (with waiting for the correct answers). Getting the 302 error. But then doing all commands a lot slower with waits of 2 secs in between it suddenly started to work. Apparantly the SIM900 needs more time after it answers, or something.

I've got a working local website that takes in HTML form data.
The fields are:
Temperature
Humidity
The server successfully receives the data and spits out a graph updated with the new entries.
Using a browser tool, I was able to capture the actual POST request as follows:
http://127.0.0.1:5000/add_data
Temperature=25.4&Humidity=52.2
Content-Length:30
Now, I want to migrate from using the human interface browser with manual entries to an ESP01 device using AT commands.
According to the ESP AT-commands documentation, a POST request is performed using the following command:
AT+HTTPCPOST=
Find the link below for the full description of the command.
I cannot seem to get this POST request working. The ESP01 device immediately returns an "ERROR" message without any delay, as though it did not even try to send the request, that the syntax might be wrong.
Among many variations, the following is my best attempt:
AT+HTTPCPOST="http://MYIPADDR:5000/add_data",30,2,"Temperature: 25.4","Humidity: 52.2"
With MYIPADDR above replaced with my IP address.
How do I translate a post request into ESP01 AT command format, and are there any prerequisites needed to be in place to perform such a request?
I did connect the ESP01 device to the WiFi network.
Here's the link to the POST AT command description:
https://docs.espressif.com/projects/esp-at/en/release-v2.2.0.0_esp8266/AT_Command_Set/HTTP_AT_Commands.html#cmd-httpcpost
The documentation says:
AT+HTTPCPOST=url,length[,<http_req_header_cnt>][,<http_req_header>..<http_req_header>]
Response:
OK
The symbol > indicates that AT is ready for receiving serial data, and you can enter the data now. When the requirement of message length
determined by the parameter is met, the transmission starts.
...
Parameters
: HTTP URL. : HTTP data length to POST. The maximum
length is equal to the system allocable heap size.
<http_req_header_cnt>: the number of <http_req_header> parameters.
[<http_req_header>]: you can send more than one request header to the
server.
You're sending:
AT+HTTPCPOST="http://MYIPADDR:5000/add_data",30,2,"Temperature: 25.4","Humidity: 52.2"
The length is 30. The problem is that everything after the length is HTTP header fields; you need to send the variables in the body. So the command is:
AT+HTTPCPOST="http://MYIPADDR:5000/add_data",30
followed on the next line by after the ESP-01 send the > character:
Temperature=25.4&Humidity=52.2
Because you passed 30 as the body length, the ESP-01 will read exactly 30 characters after the end of the AT command and send that data as the post body. If the size of that data changes (for instance, maybe the temperature is 2.2, so one digit less), you'll need to send the new length rather than 30.
I am working on a program than launches Jenkins jobs using the REST API. After the job has completed, I'd like to get its log, so I call http://jenkins.domain.com/job/my_job_name/#/consoleText in my code.
In 75% of the cases that works and I get the text in return. But there a some cases where it comes back with HttpStatus 100 and no text. (Opening the URL with the browser then shows the text, so clearly there is something to return.) (I haven't found any pattern that would explain it, like "exceptionally large log" or so.)
I found no documentation about calls returning 100 and have no idea how to proceed. Simple repeating the call gives the same result. So how can I get the expected result?
Surprisingly "exceptionally large" was the answer. This caused a timeout (followed by some inappropriate handling) in the library that I used to handle the HttpGet. (Fortunately it was fixed very quickly.)
I have a perl code that sends a reminder sms via Net::UCP package. It worked so far, until now, I started to get negative acknowledgement with 02 reason code. The EMI UCP documentation says, it refers to syntax error, but I don't know why. It worked for like 6 months. Here is the sent string:
02/00454/O/51/0036204802483/36303444080/////////////////3/8/5469737A74656C7420DC677966656CFC6E6B21200A0A54E16AE96B6F7A7461746A756B2C20686F6779206C656AE17261746920534D5320737A6F6C67E16C746174E173756E6B20746563686E696B6169206F6B6F6B62F36C206D6567737A3F6E696B2E200A4BE9726AFC6B2C206B69656D656C74656E2066696779656C6A656E2061207AE16C6F676A65677965206C656AE1726174E172612E200A0A5469737A74656C657474656C3A200A42C1562050E96E7AFC677969205A7274////1////1139/////04
And here is what I receive:
02/00022/R/51/N/02//07
My question is where is the syntax error in the sent string? Thanks in advance!
It was the MB parameter that was set to 8. I also noticed that a new message was uploaded that was too long, was longer than 160 characters, so I told the client to change it.
I am building a mailout capability and it is working OK as far as it goes. However, I want to distinguish between various potential (high level) outcomes in order to determine what happens to each message after the current send attempt.
This must be a common requirement so I seem to be missing something pretty obvious, but I can't find anything that addresses it, either here or via Google or on PHPMailer site or .. . Possibly because there are so many questions about specific errors that I just can't find anything useful in all the other results.
At very high level:
Attempt send, and assess resulting error/result. Identify whether this message has been sent, must be retried later, or failed permanently.
- success -> update message status as 'SENT: OK'
- sent, but some issues (e.g. one recipient failed, others processed OK)-> 'SENT: some error'
- failed, due to temporary problem (e.g. connection problem, attachment open) -> 'TRY LATER'
- failed, due to message-specific problem that we should NOT try to resend-> 'FAILED: some error'
As I was unable to find an existing resource with e.g. a table of errors, I spent some time working through the phpmailerException code to try to build one myself, but it's not simple because a) they don't appear to have been designed in terms of this kind of grouping logic, b) it is not easy to uniquely identify a particular error: PHPMailer provides human-friendly messages, which are different in different languages, rather than an identifiable code - given that my solution will need to work across different language installations that's a problem!
Obviously SMTP itself provides a range of errorcodes which I could potentially use for this purpose, but how do I access these via PHPMailer? (This would work for me as I only use SMTP at this point - however, this would NOT work if other message transport like sendmail was used, so I would prefer a PHPMailer solution)
If you want individual result codes for individual address, you really need to send each message separately. If you do get errors on some recipients, they will be listed in the ErrorInfo property - look in the smtpSend function to see how the error string is assembled. I agree that it's not especially easy to parse that info out. The error messages in PHPMailer are generally more for the developer than the end user, so the translations are not that significant. You can get slightly more information about errors if you enable exceptions rather than relying only on return values.
I am facing the problem while running the AT-commands in Hyperterminal when i enter the following commands
AT
AT+CMGF=1
AT+CSCS="GSM"
AT+CMGS="03215836031"
>TEST <CTRL-Z>
it returns the following result
Result: +CMGS: 136
and i received the sms on my cell.
but when i use the following sequence of commands it gives me the error
AT
AT+CMGF=1
AT+CSMP=17,167,0,8
AT+CSCS="UCS2"
AT+CMGS="03215836031"
Result: +CMS ERROR: 305
I don't know what is going wrong with these commands. i have googled a lot but not find any solution.
+CMS ERROR: 305 is a text format mode error.
AT
AT+CMGF=1
AT+CSMP=17,167,0,8
AT+CSCS="UCS2"
AT+CMGS="Unicode" Mobile no and SMS text must be convert to hex code.
I have tested successfully and sent SMS to any language.
