IoT Cricket looks very interesting
/This looks like a very interesting device. It’s called the IoT Cricket from Things on Edge. It looks like it brings Lora levels of battery performance to a WiFi connected device. It apparently has the ability to wake up, connect to a WiFi network and push out a packet of MQTT data in around 8 seconds. Which is pretty darned fast. There is only very simple PIO available for data inputs but there is onboard temperature and a clock that turns everything off between readings. You can power the device from one or two AA batteries or a LiPo and they are talking about battery lifetimes in the months and years.
It’s only 16 quid to get one, which will be a good price if it does what they claim. I’ve ordered one, looking forward to having a play.
