UART readings from Sky

Developers
1

I had a Sky lying around that has been replaced due to problems with the haptic sensor. On the PCB i saw an RX and TX with the description UART. Decided to hook up an USb TTL interface i had lying around.

Powering up the Sky module i could see the following communication

Dunno if anybody has done this already but i was curious. FYI i had fitted a new haptic sensor, was wondering if i could get it to work

i had to look up what a disdrometer was :wink:

Here is the UART output from the hub. I’m curious about when status messages from the sensor are triggered (with rssi value). They don’t seem to get sent regularly.
