By the PCB silk I was wrongly thinking that the module could be on of "RFM69" or "RFM69H" or "RFM69W" and "RFM69HW".
Now if I understood correctly the diagram, the module can only be either the "RFM69W" (low power 13dBm) or the "RFM69HW" (high power 20dBm).
Since this module has the "H" marked it should be "RFM69HW" and that is confirmed by the other side of it, because it has the two additional black ICs.
@Vertorix said in Vertorix - Easily Create your Own Mesh Network with Sensors and Controllers:
I have created a new IOT project which allows the user to easily create a mesh network of sensors and control End devices.
All programming of devices is done in the open source Arduino IDE, and there are already libraries and examples available. It's really easy to make your own network because all the mesh network side is automated. There is no stuffing around with complex wireless libraries, you just take your sensor readings and send them.
You can use Node-red to create Dashboards and forward messages to MQTT etc.
See Documentation here: link text
The VT1100 in sleep mode consumes 7uA, so can run on battery for years.
I'm trying to gauge interest in the project. If there is enough interest I will sell the devices cheaply.
thanks my issue has been fixed.
@evb it's for doing a gasmeter, counting with a reed sensor.
But for my tests, the read sensor is not connected. So nothing wakeup the interrupt.
I just send every 10 minutes the counter, as a keepalive. (Domoticz don't put the sensors as "red" )
First, I was doing test with newbie pcb, and I had strange values.
So I remove everything, and I do test with breadboard and dupont cable.
I just have the arduino pro mini, and the rfm69 solder on a nrf2rfm69 board and a 0.1uF capacitor.
I have 2AA alkaline battery, connected to the VCC/GND pin of arduino and to 3.3V/GND of NRF2RFM adapter.
I measure the current on the cable between battery + and 3,3V of NRF2RFM69 (like in your photo)
I have no scope, so I can't check NSS/MOSI/... and so on. But the transmissions are OK, and everything is working well, except current when sleeping.
I had no time today to do more test today. I will double check everything as soon as possible, try your sketch
@martim said in RF Nano = Nano + NRF24, for just $3,50 on Aliexpress:
@TheoL way to expensive.
For less money, and very little effort, you can put your own together: https://www.openhardware.io/view/480/Compact-nRF24L01-Pro-Mini-Bottom-Shield
As demonstrated, it also gives you more choice and control over the type/quality of nRF24 module that you get.
