Can't send data with a UDP socket as a broadcast

[dimfred]

Hello,

I have posted the question on stackoverflow. Hope that maybe someone here can help.

https://stackoverflow.com/questions/558 ... e-on-esp32

Main thing is I know in my example, that my server works. When I send data over the terminal as a broadcast the server receives. My socket also works, because on sendto it returns the correct number of bytes. I have no idea what the problem is. Is there anything in the config I have to enable to allow a broadcast leave the esp32???

Open for any suggestion

Hi, Dimfred

Thanks for sharing the issue, and also saw you seemed to know how this issue happened on the website of https://stackoverflow.com/questions/558 ... e-on-esp32. Thanks.

Hello Alvin,

thank you for your response.

Now I have another question, since I still have problems of acquiring the antenna for wifi, while the a2dp sink is active. Could you maybe explain some steps on how I could achieve my a2dp sink + sending wifi? I am currently sending ~2 packages/min, but have ~3000/min coming from the a2dp. So not the best rate

I thought of looking for a a2dp sink task semaphore, but I couldn't find any. Would be great if you could help.

Greetings Dimfred

Suggest you open a different topic for that, as it has nothing to do with UDP broadcasts.
