UC20-G RAM write

Hello, how can I write file to RAM through AT command? I saw an example in manual but don’t understand how to use it. I’m using PIC to gather some info and repack it and then want to store in UC20-G ram then upload it when interval reach. How can I do it?

Hi @MangMuang
Could you please take a screenshot of your operation process to show it, so as to find the problem more easily.
