Hi All,
I'm searching information about the possibility of sending data from llm630 via espnow. is it possible? if yes, how? I need to hard modify the pcb?
ciaoo

Hi,
The LLM630 is a sensor module, and ESP-NOW is a communication protocol used by ESP32/ESP8266 devices for low-power, peer-to-peer wireless communication.
To send data from the LLM630 via ESP-NOW, you need a microcontroller with ESP-NOW support (like ESP32) connected to the LLM630 sensor to read its data and then transmit it over ESP-NOW.
Key points:
The LLM630 itself doesn’t support ESP-NOW directly; it only provides sensor data (usually via UART, I2C, or SPI).
You don’t necessarily need to hard-modify the PCB if you can interface the sensor’s output with an ESP32 development board or custom PCB.
Your ESP32 firmware will handle reading data from the LLM630 and sending it over ESP-NOW to other ESP-NOW-enabled devices.
If you want to avoid hardware changes, you could connect the LLM630 to an ESP32 via existing interfaces (e.g., UART pins) and implement ESP-NOW on the ESP32 side.

@henryCharm tnks for answering.. I'm talking about this LLM630 .. I red somewhere this llm630_compute_kit has a esp32 for wifi tasks..
