All you out there with Arduino microcontroller experience: Maybe you have some thoughts on the question at this link. I sure am stuck. Thanks Much.

Yes, it is possible to transmit image data using the Arduino Portenta H7 combined with a Vision Shield and LoRa technology. The Arduino Portenta H7 is capable of running Python and can be used to capture an image from the Vision Shield’s camera and to process it in Python. Once the image processing has been performed, the Arduino Portenta H7 can then transmit the resulting image data over a LoRa or Long-Range Radio link.
From what I have read and experienced, the H7/Shield combination will not perform point-to-point communication. It will only communicate via a LoRaWAN network. That and the fact that the camera is grayscale makes this device unsuitable for my purposes. Am presently looking into ways to connect two Uno/Mega boards so that they communicate directly with each other. Exploring this path because mounting a camera and a LoRa transceiver on the same board has not worked since they use the same pins.
If anyone wants to use the device on LoRaWAN, a means of segmenting the image into LoRa-sized messages, to include CRC verification, is presented in CaptureAndSendFrames_Uploaded within https://github.com/SoothingMist/Arduino-Based-LoRa-Sensor-Network.
