Hello

Can I get access to the low-level RF encoder/ decoder on the ESP32- C3? I would like to transfer and receive my own signals applying the 2.4 GHz antenna, outside of the Bluetooth/ wifi protocols. The reason I need to do this is for an ultra-low latency application in which I simply want to send extremely simple information (a single yes/ no) and there’s just one transmitter and one receiver in the location where my product will be deployed.

Thank You

    Hello,

    Yes, the ESP32-C3 microcontroller provides access to the low-level RF encoder/decoder functionality for custom transmission and reception on the 2.4 GHz frequency. The ESP32-C3 is equipped with a Wi-Fi/Bluetooth subsystem, but it also supports other communication modes, such as RF communication using the RF module.

    To use the RF module for your application, you would typically need to bypass the higher-level protocols like Wi-Fi and Bluetooth and directly control the RF interface. The ESP32-C3 provides a general-purpose radio (RF) peripheral that can be used for this purpose.

    Thank You

    Hello,

    Here are some things to consider for designing an antenna on an ESP32 PCB board:

    01. Determine the frequency range you need. The most common frequencies for ESP32 are:

    • 2.4 GHz for WiFi
    • 433 MHz for low-power communication

    02. Decide what type of antenna you need based on your frequency range and application:

    A. For 2.4 GHz WiFi, a chip or PCB antenna would work well. Options include:

    • Chip Monopole Antenna
    • PIFA (Planar Inverted F Antenna)
    • Inverted F Antenna
    • Patch Antenna

    B. For 433 MHz, a simple wire antenna would likely suffice.

    Hope this advice on ESP32 antenna design helps! Let me know if you have any other questions.

    Thank You

Hii, I have the raw ESP32 S3 with a self-made Inverted-F antenna.
I can scan for different WiFis and can discover quite a some with fine signal strength.
I can not, still, connect to any WiFi. It tries to connect forever. Even when I get really very close to the router.
similarly, creating an AP doesn’t give an error, but the AP doesn’t become visible when scanning with other devices.

I assume there’s some error that prevents me from * transferring * anything.
What could be the issue?

Thank you in advance.

    Hello! It sounds like you’re having trouble connecting your ESP32 S3 to WiFi and creating an access point. There could be a few different issues causing this, but here are a few things you could check:

    1. Make sure you are using the correct WiFi credentials. Double-check the SSID and password you are using to connect to the WiFi network. If you’re not sure, try connecting to a different WiFi network with known credentials to see if that works.
    2. Check that your antenna is properly connected to the ESP32 S3. Make sure the antenna is securely attached and that the connection is not loose. You could also try using a different antenna to see if that solves the problem.
    3. Check your code to ensure that you are properly configuring the ESP32 S3 to connect to the WiFi network or create an access point. Make sure you are using the correct libraries and functions to connect to WiFi and create an access point.
    4. Check the power supply to your ESP32 S3. Make sure it is receiving enough power to operate properly. You could try using a different power source or adding a capacitor to help stabilize the power supply.
    5. Try resetting your ESP32 S3 to its default settings. This can sometimes help clear up any configuration issues that may be causing the problem.

    I hope these suggestions help you get your ESP32 S3 up and running! Let me know if you have any further questions.

    Thank You

    Hi Vikas, you can download the modules' reference designs from www.espressif.com/en/support/download/documents, ESP32- WROOM- 32D and ESP32- WROVER- B have the latest antenna designs. You may also directly use modules unless you have reasons for designing your own layout.
