Can't communicate two devices and ESP8266 in APMODE over UDP broadcast RTOS v1.5

[domecar]

Hi! im trying to communicate two phones over UDP protocol sending broadcast packets but with RTOS v1.5 i can't do this. If i change to NONOS works perfectly! what could be the problem?

this is my code, for RTOS (I edit it because is long) Cellphone 1 is in port 3331 and cellphone 2 is in port 3332. if i send broadcast data from Cell 1 to 2 it never come. but if i send to ESP AP at port 3330, data arrives perfectly to ESP. I cant comunicate between clients.

What could be the error?

Thanks!!!

For RTOS SDK, you need to call espconn_init first to use the espconn_xxxx APIs. You can have a try with it, maybe it can solve your problem.

Thanks for your response! I edited my code with espconn_init(); but unfortunaly still not works!

Hi,

Sorry that this feature has not released on ESP8266 RTOS SDK, it is only on the non OS SDK now.

We will add it in the future release.

So sorry for the inconvenience.

[domecar]

Thank you very much!

I'll wait for it!

regards!

Sorry if this is not the correct place to post the problem, but i have a problem with esp-open-sdk compilation. When i try to compile the IoT_Demo example from ESP8266_NONOS_SDK_V2.0.0_16_08_10 folder, I have this error.

Code: Select all

../Makefile:136: warning: overriding recipe for target 'clean'

../Makefile:122: recipe for target 'crosstool-NG/ct-ng' failed
make: *** [crosstool-NG/ct-ng] Error 2


I editted code because it was in spanish. This is English Version of output when i try to make the example.

I don't know what is happening, could you help me?
