For sure I will ...

Wireless communication between sea-water submerged wearable and esp32 above surface
Hello,
I am working on a project that requires the communication between a wearable (e.g. wristband) that is submerged in shallow sea-water (no more than 30 - 40 cm) and an esp32 that is a slightly above the water surface (about 1 - 2 m). These devices shall exchange few Kbytes / minute. I tried my ...
