Re: Esp32 433mhz communication

I just want to receive one a float as string once every minute and dont know how to do it :) RMT is too complicated for me, and all the examples are only for how to read NEC codes, so im gonna adapt the Arduino library for my needs.

Re: Esp32 433mhz communication

Could you share the config? I still cant figure out how to tune it to read 2000bps from RadioHead.

Re: Esp32 433mhz communication

Thank you for your effort Peter! I will try the basics. Now i print all the channels to the console and am seeing alot of traffic, even with the transmitter turned off, but its useless to me.

Re: Esp32 433mhz communication

Well, i am completely lost :) I didnt know that implementing this "simple" communication is so hard(for me). I have no idea how to use RF transceivers between different platforms and libraries. The only examples for the RMT lib are for NEC remotes and NeoPixel. I just cant believe that nobody is con...

Re: Esp32 433mhz communication

I decided to switch the Arduino lib to RadioHead's RH_ASK Image as there the docs are cleaner and just started to diving in it :)

Re: Esp32 433mhz communication

Well, im gonna need some more help guys, as im too bad at radio waves, modulations, etc :) Im gonna send a signed int/float for temperature. Lets say i use the VirtualWire lib on the Arduino nano transmiter for which I've found the following info: http://www.airspayce.com/mikem/arduino/VirtualWire.p...

Re: Esp32 433mhz communication

Thank you guys, i have NO experience with any transmit/receiver module, but im very interested in it, as i need low power one way connection to my esp32 board. The transmiter could be any other architecture . The RMT module looks as good start, i already made a voltage divider for the receiver data ...

Re: Esp32 433mhz communication
