Robustness of a Frequency-Diverse Network When One Frequency is Unusable

Bhavik Joshi

One thing that I wanted to do this week was to validate the effect of including frequency diversity in the network that we made for our robots. So, I programmed one ESP32 feather board with a 433 MHz packet radio on its stack to send out a lot of garbage values over the 433 MHz band extremely quickl...

Mesh Network: What is the best way to create a mesh network for our blimps?

Bhavik Joshi

Over the past week, I have been looking into what are the best tools/ways to create a mesh network for our ESP32 boards that will be attached to the blimps. The three frequencies we want to add to diversify are 2.4 GHz, 433 MHz radio, and mmWave 20 GHz. For the 2.4 GHz option, ESP-now looked like...
