My my, interesting day. MQTT connection from farm was going timing out every
hour on the hour and triggering my "Oh shit there's an issue at the farm!"
alerts.
Still haven't quite gotten to the bottom of it, but reducing the timeout has
made it a tolerable condition for now.
Pushing forward with some FreeRTOS learnings - also hooked up an Arduino to act
as a TTL-to-USB device, which is good, I don't need to buy more random usb
devices.
The next trick is not accidentally connecting the programmer and the TTL-to-USB
at the same time and blowing the STM32 - glad I got spares, I know I'll do it
eventually.
Kenya trip looming ever closer, got the camera gear in order last night,
discovered I was missing a lens cap, so printed a new one off to great success.
Tonight I need check that the drone and controller don't need a firmware update
(as happens literally every time I use it...) and also make sure I've located
all the chargers for the various cameras.
