Unable to Change Read-Only Property of a File using Cinterion® ELS61-E-R2 AT Command Set | Telit Cinterion IoT Developer Community

May 3, 2023 - 9:46am, 60 views

Hi all,


I am currently working with the Cinterion® ELS61-E-R2 module and I am having trouble finding the AT command to change the read-only property of a file in the AT Command Set documentation. I need to change the read-only property to truncate the file. Here's the link to the documentation I am referring to: (here the link). 

To truncate the file, I am using the command:

AT^SFSA="open","a:/",18     , where truncate= 16, read/write= 2


Below are the outputs of the AT^SFSA="stat","a:/" and at^scfg? commands:


Output of AT^SFSA="stat","a:/":

^SFSA: 26
^SFSA: "23/05/02,13:52:42"
^SFSA: 1
^SFSA: 0


Output of at^scfg?:

Does anyone know how to change the read-only property of a file using the AT Command Set for the Cinterion® ELS61-E-R2 module? Any guidance or alternative solutions would be greatly appreciated.

Additionally, if there is any other information that could be helpful in resolving this issue, please let me know.

Thank you in advance for your assistance.
