Hi,

1. I am using SOCKETS to make big file upload from my device from server. I have 2 questions:

a) What is maximum buffer size in module for SOCKET? It seems about 1K. After it makes unstable in operation

b) What is maximum speed of upload using sockets? I am acheaving 5-10 Kb/sec. It is too slow for me.

I send 800 bytes in socket. Wait for OK. Then send next part. Sometimes I see delays/timeouts about 1.5s while awaiting ''OK'' from module. Or there is no OK at all. What's reason?

FW version = 140128-caf4b79-SPWF01S

2. I am single developer (not a company). My distributor ignored me. Can you push them to send me fresh FW? Compel, Saint-Petersburg, Russia. My mail dimitrybulkin@yandex.ru

Ciao, Gerardo

Thanks for Phyton script. But result of using is the same to my experience with embeded.

When I send small file ~2 kb to my server all is OK. When I send big file 500 kB I see that module go into some kind of fault and reset. Using embeded I can see some codes with info where fault happens. With Phyton I just see reset +WIND messages, no codes.

It is possible to avoid fails if I send trough embeded with this algorythm:

Open socket

Open file

In cycle{

Read file into buffer. Buffer must be not bigger than 450 bytes

Send buffer with socket

Wait for OK response

}

But after sending about 2-10 kB speed reduces. Because OK responce will can be after 0,8...1.5 seconds. So problem is not in boudrate of UART/

I am very interesred to send big files to my server. So now I will devide big files into 2KB blocks, but it is bad solution. Help me to understand problem. Or if it is problem of module I am ready to help you solve it with my colaboration. I am realy like your module comparing Digi, microchip and TI solutions.

I am ready to give you:

1. access to my web server for tests

2. files I am sending

3. my sources an explain them

But not in forum because in files info how to acces to my server.

Enter your commands below.

Insert ''exit'' to leave the application.

Insert the name of the command (help=display the whole list, exit=close the APP)

: sockopen

Insert the target host: [HIDDEN]

Insert the TCP/UDP port: 80

Insert the socket type <t for TCP | u for UDP>: t

ID: 00

OK

++++++++++++++++++++++++++++++++++++++++++++++

If you see something like this:

ID: 00

means that the socket 00 is correctly opened

Insert the name of the command (help=display the whole list, exit=close the APP)

: sockwrite

Insert the file source <console|localfile>: localfile

Insert the socket identifier <from 00 to 07>: 00

Insert the filename (the file must be located in the same shell folder): small.d

at

OK

Module was connected to usbe trough http://www.terraelectronica.ru/pdf/CHIP45/LITTLEUSB.pdf

Power is taken from DISCOVERY STM32F4 with 407 controller connected to USB trough miniusb (debuger)

I have only suspection that DISCOVERY can't give enough power to send 500 kb file. Will make big capacitor in power circut and report you. But wifi module do not report that there is not enough power.

So now if I send ~500 kb file with buffer 460 bytes

I have low speed because of big delays to recieve OK from module. And mostly sending is OK

And if I use 2048 bytes buffer I see... same. But few hours ago there are was messages about reboot! I made power off/on for module physicaly. Maybe that is reason. And remark: 2048 buffer is not faster than 460 bytes buffer.

Firmware is 140512-complete - FW3.0

You had right FW from Compel, and Python scripts too, so, you can now start evaluating SPWF01S features.

ST RF team offers technical support on WiFi module and related tools.
