Lab-08 Believer Comms and Firmware
For this lab, we set up the RFD900X telemetry module indluidng the specifications. We first found out what type of frequency it uses as well as what other features the RFD900X has. We learned more about how the USB serial connector pin and how this usb module connetcs with modern comupters, offering inter communication within the module towards the desginated website. We printed the labels for both ground and air units and started connecting out modules using the software PuTTY on both computuers. Overall, we installed the firmware from the computer and saw our aircraft hardware connect to the designated computer.
Step 1: The first step is to set the module to its proper frequency. This module uses the frequency 902-928MHz frequency band which can communicate over long distances. You must also install the antennas so they protect the module from damage.
Step 2: The second step is to connect tothe two computers for this lab. In order to do this, we used the USB serial pug, which connects to modern computers.
Step 3: After connecting the ESB serial connector for the telemetry module, we installed RFDTools on the PC and modified the setting in RFD900

Step 4: After we modified the settings we used the firmware called PuTTY which connected to the serial port are were able to test out this firmware by typing Hello word on the software.
Step 5: We pulled up another software called ArduPilot and used a mission planner, which did not have any effect on an open mission planner, but rather private.
Step 6: We finally installed all firmware
Step 7: For this step, we finally tested our module on the Windracers ground station app and created a new connection for this lab.
Overall, we learned how to properly install and modify a telemetry device as well as install and link our module to different software’s. I was confused at first how linking our module to one of the computers worked and was curious how we were able to get data from a static module to date online. After my team explained to me how it worked, I was able to grasp how linking our ESB serial connector with modified settings worked.
