Hello. Help you for your video. Everything works ok, but i can only create or rewrite the existing file. I cant append it. I tried to use "appe" flag for ftpputopt but, if file exists it returns "operate error" and If it does not, it creates one and writes to it, so the flag "appe" does not work. So i only can create and write to file, them when i connect to ftp again, i have to create another file because If i write the previous one, it rewrite it. So for now, i dont know what to do.
hello sir , i do i send image bytes from ov7670 using sim800l ftp i have tested the camera and sim 800 are working well but now merging them is the problem
Hello Ravi, How to put some audio files in the internal memory of the module with the USB port of module.and can we access the file system of the module in PC via USB or something other?
Yes, I somewhere saw that you can store files on SIMCOM module flash. There are commands for that. I am not aware of them as of now. But its there. Need to dig them up :)
If anyone come across error 66 or something similar. Make sure you have an active internet connection. My plan expired just 1 day before trying this tutorial and was getting timeout error.
Good afternoon, Ravi. Tell me how to transfer to a new line in a text file? Let's say 1.txt writes several data and each time from a new line, and not in one line. thanks
Yes thank you ! Just found the corresponding AT command : Delete file -> AT+ FTPDELE and I am not 100% sure but this one AT+FTPEXTPUT is used to append data to an existing file. Correct ?
Hi Max, I thought FTPPUTOPT is used for appending the file or overwriting. Not aware of the FTPDELE command, Could you please try it out and let me also know ? I am not finding this command in datasheet.
I didn't try yet these commandst. But I found it into the SIM900_IP_Application Note_V1.03 :). This link provide it -> sim-moduly.cz/download/soubory/sim900/201212516746f.pdf
AT+FTPPUTOPT command sets up the how the FTP PUT is to be treated by the remote server. The options are "APPE" (for append file), "STOU" (for store unique file) or "STOR" (for store file).
+chansokong keo For appending to a already existing file you should execute the command AT+FTPPUTOPT="APPE" before executing the PUT session. You can find details about the command in the manual
Hi, i am using SIM800 for FTP application. I have successfully uploaded file on FTP server.But sometimes for AT+FTPPUT=1 command i get only"OK" response .So in that case should try AT+FTPPUT=1 command again after 60 seconds timeout or should try AT+FTPPUT=2,10.what is the right method??
+Ravi Pujar .Thank You.If i get only "OK" URC for first attempt of FTPPUT open session command then i tried same commnad after 60 seconds timeout,in that case i get +FTPPUT=1,66 ie operation error.But instead of this if try to request forcefully FTPPUT=2,10,i get response +FTPPUT=1,1,1360.So i can put data now. .I came to above scenario some times only. Plz help me what i have to do. My FTP application is working very well.I am using it for data logger.I have uploaded so many files within first attempt of FTPPUT open session command(in that case complete URC is received OK+FTPPUT=1,1,1360).
Hi,I am using SIM800 for an application.I am able to put the file on the server by using these commands, but the server cannot access them. Can you help me out?
+Abhijit Bhagwat Hi, What you mean by server cannot access them, Which program is not able to access it?. It must be a issue with permissions on the file. If file uploaded as root user then normal users cannot access it.
Abhijit Bhagwat Please take this question to stackoverflow.com. forum. Looks like a web server issue. You will find lot of experts there. I have very little experience on the web server part.
Dear Mr. Ravi Pujar, good morning. I am having problems in transmitting a text file with the SIM800L, the file arrives empty on the FTP server, the file is on an SD disk. The program I'm developing is identical to your orientation of this video, until the moment that the Lord writes Hello12345, at that moment, in my program, I want to list the contents of the file that I have already saved in the SDcard and that was written to the file entered on the FTP server. Where am I going wrong? Can the Lord help me with guidance on how to proceed? Thank you in advance.
Hi, I did this video long back. Havent tried listing, But you can use the command AT+FTPLIST to get the list of files in a directory. You can post this on the www.embeddedadvice.com forum. We can discuss. Dont forget to share and Subscribe :)
Im also about to start gprs stuff for my data logger and your video just gave me heads up.

Hello sir how do you send large file like 300kb using At command

I guess you could just send
to. Insert new line
@@RaviPujar So the fact of the matter is that it does not work like this - example 1234
@@ЕгорМастеров-х3ч it's not text characters. You need to send binary data.
@@RaviPujar do not give an example? I will be grateful
@@RaviPujar This is done through the command AT+FTPTYPE ?
i am trying retrieve image from ftp..Is it possible ?
I am trying to upload image to ftp... Is it possible? ;)
Very useful explanation. But does it possible to delete files or append data to an existed file with simcom module ?
Hi Max, Yes it is possible. You can set the mode while using FTP. There is a command for that
Yes thank you ! Just found the corresponding AT command : Delete file -> AT+ FTPDELE and I am not 100% sure but this one AT+FTPEXTPUT is used to append data to an existing file. Correct ?

+Ravi Pujar Thank you so much :) :) :)

My FTP application is working very well.I am using it for data logger.I have uploaded so many files within first attempt of FTPPUT open session command(in that case complete URC is received OK+FTPPUT=1,1,1360).
It is ok to expect such behaviour on 2G network, You should put retry mechanisms until it is sent
Hello Abhijith.. which terminal you are using
where you are executing these commands ???

I get a message on my server that the file is locked up by other process.
But I can see the file and its size on the server!
