Autonomous Buoy — release 1.1.6
This release is the outcome of the trials carried out over the summer to prepare the upcoming LoRa Ground Station. To test the link that will one day connect the station to all eight buoys, the real-world range of the 433 MHz radio had to be measured precisely — and those measurements led to revising several settings that already benefit everyday use with a joystick.
What's new
A faster radio link with four times the data rate
Six different radio data rates were compared on the water, at increasing distances. The rate selected, 9.6 kbps, is the one that reaches the farthest — and it is also the only one compatible with the traffic of the future ground station. The previous setting was 2.4 kbps.
The most recent trials hold at least 150 metres with no message loss at all, with a good antenna and careful cabling (see below).
