EHS6 Speed Rate of read from FSS to UART | Telit Cinterion IoT Developer Community
March 5, 2018 - 4:53pm, 2532 views
I need to save a file from FSS of the module to the memory of my embedded system, It's a file of about 2MB, currently to do that I use AT commands, in details after opening of the file, I use:
AT^SFSA="seek",0,..
AT^SFSA="read",0,1500
Sniffing the UARTs, I saw a 300ms delay on each read operations, this delay sometimes increase drastically and with this delay and the limit on the buffer size a simply copy of 2MB it takes 5-6 minutes.
Is there any other methods in order to access to a file on FFS?
Hello,
Indeed it might take some time as you have to call an AT command for each 1500 bytes.
You could probably use OBEX protocol which is used by MES tool.

Thank you, is there any documentation or example of that protocol on EHS6?
Hi,
Please have a look:

Hi,
Have you try with at^sjdl command to tranfer the file from your operating system to the FFS?
example
AT^SJDL=1,1870,"JRC-1.50.11.jad"
Tranfer the file to the FFS called JRC-1.50.11.jad, this file has a byte size of 1870 Bytes
