What I’m researching is - operate 5 LEDs, controlled with a Nano, and ESP8266 mounted on a bicycle with a Uno, ESP8266 and 5 push buttons in a follow automobile, push button will activate corresponding LED. Plan on using a WiFi router mounted in the auto, powered by a 12v to 120v inverter.
Looking to transmit about 100 meters or more if possible. Could add an antenna on the automobile but would rather not on the bike.
Other option is using nRF24L01 units.
I’ve ordered parts however they are on the sloooow boat from China.
I have no need to connect to the internet.
I’m just looking for thoughts while I wait for shipping. I now realize the small savings doesn’t really offset the time and lack of communication.

- Sun Dec 23, 2018 4:17 pm #79692 WiFi might be a bad solution for your project as I think there is no demand for high datarate.
Look at LoRa devices, they provide long range with good reliability.
Then you can allways decide to do the rest based on Atmel or Espressif arduinos, depending on the power available and processing power needed.

- Mon Dec 24, 2018 2:10 pm #79698 Why not use 2 ESP8266 loaded up with ESPnow. No need for router/inverter/nano.

This "might" be possible with esp modules and external antennas using highest tx-power.
It is more likely to work reliable with LoRa modules, due to applied technologie. WLAN was not designed for use cases like that, LoRa was.
