SPWF04S Server-side-includes
Hi!
I am using the SPWF04SA module. I am trying to create dynamic pages. My webpage is done and it works. I'm having problems with updating the tokens buffer using the AT+S.INPUTSSI command as described in the AN4965 Application note and UM2114 User Manual.
The problem is, if I send more than 255 bytes with AT+S.INPUTSSI command, the module became unresponsive! No more AT commands are recognized, and after 20 seconds the Watchdog resets the module. I think this is a bug, and if the SSI tokens buffer is limited to 255 bytes, this should be mentioned in the manual and/or application note.
So, when I send this:
AT+S.INPUTSSI=256
|{1111;11/05/2017;16:00}|{1111;11/05/2017;16:00;0;1;11,00;116;0;0}|{1111;11/05/2017;16:00;116;0;0;0;6;0;0}|{1111;11/05/2017;16:00;7;1;0;2;1;0;12345;0.0.0.0;123456789012345;1234567890123456}|{1111;11/05/2017;16:00;22:32:43;33;3;8;19:42:43;32;2;65}|{012345}|I get no answer from the module, and I have to wait 20 seconds for the watchdog to reset the module.
Instead if I send this:
AT+S.INPUTSSI=255
|{1111;11/05/2017;16:00}|{1111;11/05/2017;16:00;0;1;11,00;116;0;0}|{1111;11/05/2017;16:00;116;0;0;0;6;0;0}|{1111;11/05/2017;16:00;7;1;0;2;1;0;12345;0.0.0.0;123456789012345;1234567890123456}|{1111;11/05/2017;16:00;22:32:43;33;3;8;19:42:43;32;2;65}|{01234}|I get answer and everything is ok.
So, the question: is this a bug, or the tokens buffer are limited to 255. Even if the tokens buffer are limited to 255, this is a bug, because the module is completely blocked until the watchdog reset...
I hope you have a solution for this, because we are migrating from SPWF01S to this new module, and I really need dynamic pages for more than 255 bytes.
Thank you
