RFD900x DOCS

This project aims to test configurations for multipoint connections using RFD900x radios. RFD900x radios are communication devices that utilize radio frequency technology for data transmission. Multipoint connection enables multiple devices to communicate in a network, facilitating communication between different points in a distributed system. The RFD900x Multipoint User Manual provides detailed information on how to configure and utilize this functionality, offering step-by-step guidance for successful implementation. Hardware information can be found in the datasheet.

Requirements

1. RFD SiK radios need a certain distance from each other to work
2. The Master node in the RFD can also be used as an actuator node.
3. Unlike Sik Radio v1/v2, in the RFD multipoint firmware, the master node is 1 and can be used as an actuating node.
4. According to logs, datasheet e FAQ RFDesign, Mav2 (Mavlink 2) protocol compatibility has been added to the RFD900x.
5. Firmware was used RFD900x2-MultipointRelease_V3.00MP.gbl
6. RFD Multipoint Manual multipoint
7. The parameters can be adjusted using RFD tools and/or AT commands.
