 Hey, this is how we're going to test the QDPI ESP32S2s. I'm using a Raspberry Pi to do the test, and that's because I can run ESPTool really easily over USB to program using the built-in DFU bootloader. I'm going to use a GPIO pin to toggle the boot and reset lines to do that. And ESPTool compresses the firmware, so it's really the fastest way to upload a bunch of code to ESP32. And then I run a self-test, and one thing that I do because it's got an antenna is I have an access point created on the ESP32S2 QDPI. And on the Raspberry Pi, I do a WPA CLI scan, and I look for the access point and then check the signal. My hand's in the way, so it's 50, but usually it's about 40, so that means the antenna got soldered on correctly, and this has passed test.
