The latest addition to my coin cell nodes, a PIR motion sensor based on the Ebyte NRF52805 module.
The PIR sensor is a Senba S16-L221D-2. I'm measuring around 24uA, which is higher than advertised, but with the 6-7uA from the NRF52805, should still get me 3-4 years on a single 2477.
@BearWithBeard Well there are more things in play. Making assumptions now. Most people don't want to read the trouble shooting section, they just want to be helped quickly. And from a usability perspective written documentation isn't the most optimized form of transferring knowledge. Because it is almost impossible to write things in such a way every one can understand it. A simple comic on radio trouble shooting might help more people. But again, that is just assumptions.
I always try to find the solution myself. But have seen people asking question that were documented well. In this an other forums.
@skywatch cheapest price I could find is 4,1€ by the way incl. VAT + shipping. I guess that's a good price - especially if you consider that you don't have to buy thousands of it to get that price.
A quick search revealed the LPC4300 series (LPC4310 e.g.) from NXP. That one has a Cortex M4 and a Cortex M0+ inside.
How would you solve things like certificate updates / TLS connections on a gateway with an MCU?
I use these: https://www.aliexpress.com/item/32855681042.html Well, they work, but profile is not the best for dupont (2.5mm). But for their price it's ok.
