Comments for “ESP8266 walkie talkie”

I don’t understand the insistence on digital radio. Why not analog?

@Alexis Mostly because I kind-of suck in RF design, so premade digital modules are easier :)

And things like echo cancellation and bidirectional communication are much easier to do digitally. Even digital radios don't usually transmit and receive simultaneously because it would disturb the receiver.

I'm so glad I'm following you on via. feed - super cool project, even though it didn't turn out as you'd expected.

Hm, maybe that's something for Hackaday "Fail of the week"? :-)

@Phil, yeah, it is, just got published :)

Did you try using ESP Now instead of normal Wifi? It's a much shorter protocol, less overhead. Might be better for noise and power usage, not entirely sure about data rate.

No, actually this is the first time I hear about ESP now. Sounds very interesting, but looks like there is no direct support for it in the esp-open-rtos platform yet: https://github.com/SuperHouse/esp-open-rtos/issues/653

Did you every continued on with this Project? the Hackaday Comment were full of great advices on how to solve the noise problem. I could imagine this device to work with some adjustments. Maybe even RTOS was updated in certain parts to help even so. Great Project!

Hello really loved the idea am presently working on such am a bit worry with the udp transmission of ADC output and the reception

Its neat and well studied. Thank you for sharing. At the very least you taught people like me to appreciate the intricacies and rigorousness of step by micro step circuit building and the precision needed for a project built from scratch.
