Quectel M66 SD card read issue


how to access sd card files through M66.
i can able to read sd card files using m66DS but the same way can’t use for M66 modem…

I’m sorry to reply you so late.
Could you tell me the software version of the module?

If you are using our TA card (EVB) of M66FA there is some hardware modification, please do the below changes.
Make R412, R414, R416 NC. Connect R411, R413 and R415.

Also please share the F/W version of the module, you can find it using ATI command.
