Holybro Microhard Radio integrates microhard Pico Series RF module which is capable of delivering high-performance wireless serial communications in robust topologies, such as Point to Point, Point to Multipoint and secure Mesh (Mesh not available on P840).
It uses frequency hopping spread spectrum (FHSS) technology, providing reliable wireless asynchronous data transfer between most equipment types which employ a serial interface. Fixed frequency is available on the P840 version. The radio is configured using AT commands through the Data port or using PicoConfig application through the Diagnostic Port.
P900 Radio operate within the 902-928 MHz ISM frequency band while the P840 Radio operate within the 840-840Mhz. You can select your radio based on your country's available frequency band.
I have tested using a single 2.4 GHz connection (microhard radios) on some of our test terrestrial rovers for telemetry and using a gamepad joystick for RC control. What I have experience is if the joystick is disconnected, the PWM values for servo 1 (steering) and servo 3 (throttle) drop immediately to 900, and the vehicles start spinning in circles as the steering defaults to the 900 value. Once the joystick is reconnected and enabled the PWM values go back to 1500 and the rover stops spinning. I see the Blueboat only has a single 2.4 GHz telemetry connection and it is advised to use a joystick for remote control. Have you experienced a similar issue with the Blueboat if the joystick is disconnected? I see the Blueboat uses the Blue OS and a Navigator autopilot, does this hardware/OS/Firmware solve this problem? Thanks for your time.
