Hi al,
I using EC21 to connect AWS
The cmd AT+QFUPL to save certificate key file into module, this file is not encrypted so it can be read,
I have checked EC21 not support AT+QSECWRITE, how to protect readout certificate key?

Hi @hai.do
EC21 currently does not have an instruction to protect certificates from reading and writing. Let us look forward to adding this function in the new version.
