SPIOut blocking the pipeline about esp32-spi-message-demo HOT 2 OPEN

It looks to me like for some reason (I don't know why), the SPIOut node fails to send messages to the ESP32 after a few seconds. When this happens, the SPIOut node gets backed up with messages, which then starts backing up the neural network.

I'm also experiencing a (different) issue with with SPIOut node (#20). However, if you add the line spiout.input.setBlocking(False), the neural network won't get backed up when the SPIOut node does. I know this doesn't fix the issue with the SPIOut node, but it will at least prevent the rest of the pipeline from freezing up.

Hopefully this can help until some Luxonis folks have some availability to work on the SPIOut node.

Hi @vipulkumar-developer

Can you try reducing the SPI clock in esp32_spi_impl.c

   //Configuration for the SPI device on the other side of the bus
    spi_device_interface_config_t devcfg={
        .command_bits=0,
        .address_bits=0,
        .dummy_bits=0,
        .clock_speed_hz=4000000, // Reduced to 4MHz
...

Due to some driver issues on MX side, we are seeing some issues like the one you've experienced.

We'll hopefully be able to check this out more, to resolve such issues
