Here's a similar, related project for an Arduino Pro Mini: https://www.openhardware.io/view/480/Compact-nRF24L01-Pro-Mini-Bottom-Shield

I also have project for mini.
The project have pads for battery, battery protection IC, LIPO charger USB for charging... battery voltage measurements....
But the project is not released yet, because high temperature during charging.

In the BACnet protocol, the messages are not sent directly, but pushed into an internal state machine that remembers (some) of the previously messages sent (i.e. memorize(_msg); send(_msg); ). The state machine also peeks incoming messages and can trigger a message re-send in case of a missed ACK. the difference with MySensors is that all the messages are numbered, otherwise you would not know which message of the last N sent previously was ACKed, but well.. ACKing the last similar message might be good enough. Anyway @SiLeX : if you want to try, this is not that complicated, (if you don't take into account the STREAMs) it will just costs about (1 status byte + 1 timestamp + 1 frame size) x N ; for N frames memorized.

Here is the code works with devDuino v2.2 It shows how all of the sensors on board (via com port) and also makes it possible to (expect) to download the firmware over the air. (for example through MYSController) /* This sketch is for a devDuino SN v2.2 with the support OTA http://www.seeedstudio.com/wiki/DevDuino_Sensor_Node_V2.2_(ATmega_328) and MySensors 1.5 For testing all the equipment, press the button D4 when a voltage is applied.

Awesome project, I wish I made something like this. (I actually wanted to make something like this when I was in school) Very clean and nice presentation and realization, with a lot of attention to details. All is very realistic, I can imagine that it took quite some time making it. Thanks for sharing the details!

@Ron said in Capacitive Soil Moisture Sensor: @Puneit-Thukral Thanks. I am not quite sure, so correct me please if I am wrong, but I think I am already using the MiniCore bootloader with platformIO. Or do I need to configure to explicitly use the MiniCore bootloaders? Also I have set BOD to disabled as I read somewhere that no BOD can also save battery. hi I'm not sure, but I believe I'm already using the MiniCore bootloader with platformIO. Please tell me if I'm incorrect. Is it necessary to set the MiniCore bootloaders explicitly?

@tiana I have not used it, but it is possible to create different revisions. See https://www.openhardware.io/view/4/EasyNewbie-PCB-for-MySensors#tabs-revisions as an example.

I looking with a magnifying glass at the chip, i noted that this is NOT NRF24L01+ but just a NRF24L01 without the plus. I used this smaller versions and they worked immediately. I_GATEWAY_READY message appeared. http://www.ebay.com/itm/2-4G-NRF24L01-PA-LNA-Wireless-Module-with-Ceramic-Antenna-1-27mm-/400746941364?pt=LH_DefaultDomain_0&hash=item5d4e610bb4 MySensors did post a warning on that: http://forum.mysensors.org/topic/728/radio-setup-give-check-wires/16 THREAD RESOLVED.

@TheoL No damage. Water went up about 7 feet on our lake but had another 11 feet to go to threaten our property. Biggest flooding was to the south of us. We did have a fun time hiding out in our laundry room during tornado flying up to the east of us. Also, I do not think the radio is dead - hooked it by accident to my Uno testing board and it was transmitting just fine. Love these things - very tough.
