- Tue Nov 18, 2014 9:11 am #2847 Tried latest firmware.bin Nov 18 2014
Before after changing the baud rate to 115200 the firmware would fail generating framing errors...with the latest bin this issue has gone away.
Thanks grr

tnx for great info and work...

Yesterday im starting tested ATPROTO.
When i simulate web server .. have problem with large page..

Command AT+CIPSENDI=0,"this is test" send only 250 character. True?
I have web page with 1500 character. Ok, one way is send page with part of large page...

Any other solutin for this problem?

The command line is limited to 255 bytes, so with the current firmware you can split the response into parts:

AT+CIPSENDI=0,"first 250 bytes"
OK
+CIPSENDI:0
AT+CIPSENDI=0,"second 250 bytes"
OK
+CIPSENDI:0

And so on.

Another option is to implement pass-through data mode (like the data mode of the phone line modems). It is possible, but I haven't yet done this. If you feel like tinkering with the firmware code, I can give you some pointers on how this can be implemented (there's already some basic support for data mode in my code).

edit: data mode will also require implementing flow control. So probably it's not all that easy.

edit 2: You can also replace the following line in target/esp8266/main.c

dce = dce_init(256);

with

dce = dce_init(1600);

to increase the command line buffer. But it's kind of a hack. What if you suddenly need to send a 3k byte web page?

Please change the size of tx buffer in the future firmwares.

this is my project for smart house..
