    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

    Hello,

    When the RA4M2 MCU boot process stops at the “Verify boot image” stage, it indicates that the microcontroller is unable to successfully verify the integrity of the boot image being loaded.

    Here are a few possible reasons and troubleshooting steps to resolve the issue:

    • Incorrect boot image
    • Corrupted boot image
    • Memory or address configuration
    • Security settings
    • Debugging and logging
    • Consult documentation and support

    It’s important to note that the exact steps and solutions may vary depending on the specific development environment, tools, and firmware used. Therefore, consulting the relevant documentation and seeking manufacturer support is highly recommended to resolve the “Verify boot image” issue with the RA4M2 MCU.

    Thank You

    Hello,

    It sounds like you may be experiencing some communication errors with your TLE9201SG. When you are receiving repeated messages, it could be due to noise on the communication line or incorrect timing of the signals.

    Here are some steps you can take to troubleshoot the issue:

    Check your timing: Verify that you are sending the commands at the correct time. The TLE9201SG uses SPI communication, and the timing requirements are critical. Make sure that you are following the timing requirements specified in the datasheet, and that the clock signal is stable and accurate.

    Check for noise: Noise on the communication line can cause errors in data transmission. Use an oscilloscope or logic analyzer to check for noise on the communication lines. If you see noise, try adding decoupling capacitors to the power and ground lines, or consider adding a filter to the communication lines.

    Check your commands: Double-check that you are sending the correct commands to the TLE9201SG. Sending incorrect commands can cause the device to get stuck in a loop or return unexpected data. Refer to the datasheet for the correct command codes and data formats.

    If none of these steps resolve the issue, you may want to consider contacting the manufacturer for further assistance or replacing the TLE9201SG.

    Thank You

    Hello,

    To create a transparent WiFi to Ethernet router, you will need to implement packet forwarding between the WiFi interface and the Ethernet interface. This can be done using the lwIP stack, which is commonly used in embedded systems.

    To get raw IP packets from the lwIP stack, you can use the lwIP raw API. This API allows you to register a callback function that is called whenever a packet is received or sent by the lwIP stack. You can use this callback function to capture the IP packets from the WiFi interface and forward them to the Ethernet interface.

    As you can know there are pull-down resistors R26 and capacitor C59 which probably cause malfunctioning of the I2C interface.

    However, you can test to apply the different channels of the IIC machine or the SCI module in the I2C mode, If pins P400 and P401 are already in use.

    However, one could similarly conclude from the datasheet that the STATUS pin was an open drain output, because just an output voltage low was specified, If I remember rightly. In this respect, it should have been possible to connect STATUS as a Wired- OR.
