Works with three buttons, not with four

[bphermansson]

I've changed the code to add more buttons to control outputs on my ESP03. If I use three buttons like this it works:
rest.button(2);
rest.button(13);
rest.button(12);

But if I add a fourth button with another button-line ("rest.button(14);") it doesnt work. The Gui gets messed up and the buttons won't work.

Hello, really interesting, thanks for finding out the bug! Can you tell me which ESP board you are using? It looks like a memory problem to me, the library is quite memory-hungry :)

Hi!

I use a one like this: http://www.ebay.com/itm/1PCS-ESP8266-ESP-03-Serial-WIFI-Module-Wireless-Transceiver-Send-Receive-NEW-/381374501949?

Hi again! Think I got it!
I changed "#define OUTPUT_BUFFER_SIZE 2000" in aREST.h, line 55, to "#define OUTPUT_BUFFER_SIZE 2200". Now it's working with four buttons. If I add another one, total five buttons, the Gui messes up like before. Quite sure the output data overflows the output buffer.

I think you definitely got it, it has to be linked to the output buffer. In a future revision of the library I'll make sure to resize the output buffer depending on the hardware that's being used.

Sounds great! Nice lib by the way, makes it nearly too easy to control things with a Gui and the ESP8266.

for connecting a 8 channel relay what size output buffer should be set ?

[marcoschwartz]

I still need time to find out an elegant way to integrate that into the library. In the meantime, for an 8 channel relay board you could use a size of 5000, it should be large enough.

Hi Marcoschwartz, Firstly, I would like to say its a brielent and eay to use library.
I am using your code to control a relay conncted to my ESP8266.
It works fine for about 20 minutes and then the ESP hangs. Is there a way to use the watchdog pin to reset it if it hangs?

[marcoschwartz]

@surajpearson Thanks! I haven't noticed that kind of behaviour, but sure you can include the watchdog in the loop() function to automatically reset the chip if it hangs.

Hi, I like you set-up here. it works great for the project I am attempting. I like the fact that it is all self contained in the ESP8266 and does not require an external server. I don't need that for this simple application. I was set up this project on my ESP8266, and am able to control a switch using 2 buttons just as described. However, I would like to have a single switch that simply toggles the relay on and back off after a short delay. being kind of new to this, i have been unable to figure out how to modify the code to set up such a switch.

Any chance you can provide me some pointers on how to set this up?

@marcoschwartz, Thanks for the email. I had already included a reset mechanism in the code, after which it works fine..

[marcoschwartz]

Great!
