Downloading binary files with AT+HTTPCGET

[tjaffey]

With ESP-AT, is it possible to download binary files using "AT+HTTPCGET"?

It seems that the "+AT+HTTPCGET" responses are ASCII with non-printing characters stripped out.
Is it possible to request ESP-AT to pass through the raw binary data escaped in some way?

I understand that I could use the passthrough mode to open a raw SSL socket to a webserver, but then my host processor would need to implement an HTTP client.

As a workaround, I am currently Base64 encoding the binary on the server and decoding on my host processor.
However, this adds overhead and means it's not possible to request arbitrary binary files from HTTP servers.

i think AT+HTTPCGET supports to download binary files. Could you please provide the reproduce steps, thanks.
