Not only busting my power budget but also the angst of spiralling complexity when using an RTOS. Using something like www.nuttx.org seems good as it brings a lot of benefits but I know it will be a steep learning curve, while topics like power management will probably be less than ideally dealt with.

Having said that, my project is pretty simple, initially. An RTOS will be an overkill to start with but what about later on? I'm finding this a difficult decision to make.

Now this is providing some good perspective! Thanks. What could be parallelised is any form of calculations not requiring I/O or tasks such as data compression prior to remote transmission.
