In the last installment, we managed to get the Pi to talk over BLE to the atMega, and for the atMega to turn on an LED to show that this had happened. While interesting, this on its own is of no use. We want to get a response back, too. Simply trying to use the readCharacteristic() function failed. Further investigation…

Talking to the atMega from the Pi over Bluetooth BLE
Past posts have built an atMega328p nano board with bluetooth BLE and a DHT22 sensor, and also a quick peek at Python on a Raspberry Pi 0w. Now it’s time to combine them. Make sure your Pi is up to date if you haven’t already: sudo apt-get upgradesudo apt-get dist-upgrade And make sure that you have the bluez libraries and…

I’ve programmed in many languages over the years. So many, in fact, that I’d be hard pressed to name them all, and unlikely to succeed. One of the things that I’ve learned in the process is that most of them are easy to pick up: just find a small working program or three for reference, a reference manual, and start…
