What document are the AT commands for
AT+QCFG=“usbcfg” covered in for the RM520N-GL
***Can I please get a copy of this Application Note:
RG520N-EU&RM520N-GL_UAC_Application_Note
Also, why is everything with Quectel so restrictive? You don’t have a central repository that I can sign up for to download modem firmware, manuals, application notes, and documentation. I can only send 1 or 2 messages in the forums a day. Most of the documents seem to only have “SOME” of the actual AT commands that are actually available in the loaded firmware, and you restrict the ability to simply copy and paste commands from the PDF documents. It just seems everything is a struggle to get information, details, and firmware for these devices. It’s very bizarre to me to have to go through so many steps to just get the details I need in order to validate Quectel modems and to build services around these modems so I can use them for my customers. Is it possible to get a dump of ALL of the documentation for the RM520N-GL modem?
Hi, Sir
I will check and send that document via email. Please check when you are available.
There is firmware RM520NGLAAR01A06M4G_01.001.01.001 with new “Optimized AT+QCFG=“usbcfg” to support disabling or enabling QDL and QDSS”, can you give description of new syntax, or send full PDF on my email?
