garudaonekh commented 3 years ago

hi, How far can espnow reach in case of internal antenna and as well as external antenna? I am currently using Tasmota with trouble with range in the open field.

I mainly use esp32 wroom 32U and esp8266 d1

garudaonekh commented 3 years ago

By the way, have you tried LR mode(long range mode) of esp32? I tried it but the range is dissapointing, i can Only reach 60m

timmbogner commented 3 years ago

I haven't done many range tests yet, but an early version of the system used to span about 120 meters of open field pretty easily. I haven't tested LR mode very thoroughly. Since it isn't compatible with 8266 I've been hesitant to bother.

120m is impressive. what kind of antenna used?and which board?

timmbogner commented 3 years ago

Believe it or not, it was just an ESP-01. I currently use 8266 WeMos modules generally and an ESP32 DevKit for the terminal module.

Let me try it using ESP32-WROOM 32U(External antenna) and see how far it can reach. I plan to use this module for the sensor(https://github.com/LilyGO/LILYGO-T-OI) and ESP32-WROOM 32U as gateway
