Technically, it is half-duplex since they cannot both transmit simultaneously. Both 802.11 and LoRa use CSMA/CA: there is a transmission preamble that allows a transmitter to detect when the transmission medium is busy and cancel its transmission to avoid corrupting the other, then wait for it to end before it begins its own transmission.
thank you for your video and hello from russia. please tell me, is it possible to enter mac addresses directly from the program? in "loop" can I enter the mac address from the serial port, and it is used for communication via esp now
Thanks for your feedback. I think you can by including this function Serial.parseInt() within a loop, which may be used to input the six MAC address values and store it in the elements of an array.
@@AnasKuzechie yes I was thinking about the nrf24l01+ I have afew of them. I will probably stick with the esp as I'm Rendering map tiles aswell and also storing data they just have more pinouts :)
Hi maybe you can help me, i currently have a raspberry pi running a website with some buttons on it. I want to make the buttons on the pi be able to control a light for example connected to the esp32. I thought of using a get request and using a http webserver on the esp32 but i feel like there must be a better way. Also the way i mentioned, i am finding some difficulities. How would you do this?

@@AnasKuzechie Ok sure, i will draw a small example of what i mean to simplify it on paper :) Where do i find your blog? I can't seem to find a link, only a link redirecting back to your channel
I have never programmed in Micropython, my specialty is assembly and C/C++. On the other hand, I’m interested in Python and may do a tutorial in the near future.

Your video was very useful to me. Tq for sharing.
awesome. Tank you for sharing code/knowledge
Thank you
Much thanks for whis review. What is the maximum frequency of value updates on the displays?
nice
I would like to add the RSSI value in the display of the connection in general. It seems impossible.ESP-NOW.
Can this be used to tightly time sync sensor data from each unit?

is it possible to have more than 2 boards in full-duplex ?
I believe so, since ESP-NOW supports multicast. May be a more economic solution is to use nRF24L01+ modules with Arduino

Hi, it might help if you could send me via my blog (link in the description) a block diagram of your proposed system.

@@AnasKuzechie Oh okay, i have already sent you an email aswell :) thanks for taking your time
@@aarriikknn33ll You're welcome
Can you explain any projects in micropython ?
