Hello Gang.
Thank you for this opportunity to tell of my conundrum and ask your advice. Have been working hard to understand RakWireless’ product lines. My questions basically come down to module choice to create LoRa P2P nodes with varying capabilities.
BACKGROUND
Am evolving flood-messaging within LoRa P2P. Things have gone really well. Have published papers in the peer-reviewed literature. All software and documentation is open-access. The existing hardware architecture is shown in this figure:
A four-minute video gives additional detail.
At issue with this project is that the manufacturer of the LoRa P2P transceiver has stopped making that model. Have been unable to get their latest model to work properly for a simple AT query/response to the transceiver itself, without any transmission/reception being involved.
While searching for alternatives, I am not finding anything that is from a serious vendor or that does not involve a rats-nest of connecting jumper wires. Looking at RakWireless’ product lines, I get the sense that there is potential. What is holding me back is that I do not see a way to connect an RGB camera, microphone, or other devices that generate a contiguous data structure. From reading the forum, there is strong indication that such things are possible but it is not clear to me which modules to select as the project transitions. RaKWireless’ modular approach is most welcome.
QUESTIONS
Had thought to start with two RAK-19007 Base Board, RAK-1921 OLED Display, and 2dbi rubber antenna; set for US915, per the Meshtastic starter kit, although I am not contemplating Meshtastic itself at this time.
Are there modules that allow camera connection? Am currently using a Pixy camera that connects though Arduino Uno’s SPI port. Other cameras are certainly possible.
What module allows USB serial connection, as I have done between Uno and Raspberry Pi?
Is there a module that would accommodate audio input?
Is there a different base board or transceiver that would be better?
MANY THANKS
Much appreciation for the community’s advice. Glad to cite any useful input received.
