Dear Technical Team,

I am using HL8548 sierra wireless modem, I have interfaced w681360 single channel voice band audio codec to HL8548

I read Air prime HL6 & HL8 series document , I am verifying audio related commands,  
In section , 12. Audio Commands

I have downloaded one amr file from internet, now am trying to store it in /ftp inside HL8548

I don’t know, How can I transfer the .amr file to /ftp folder from my linux host,

Could you please kindly do the needful in knowing me the AT commands as early as possible, in how to transfer my downloaded file from host to /ftp path in HL8548

As am stuck with this from many days, kindly do the needful as early as possible

Awaiting for your replies,

Many Thanks in advance again

That has nothing to do with the original title & topic of this thread - “How to store audio file ie., .amr in /ftp from host” - so start a new thread!

But, before doing that, look up the error codes in the AT Commands document…
