At all of the time 328p will be in sleep forever, when button is pressed interrupt is triggered and wake the 328p power ON the radio send info power OFF radio and go sleep forever.
Only when battery level go below critical level. the radio stay OFF and only interrupt and sleep forever.
I am almost ready with the drawings of the hardware, and next week start work on software... you can see the project in the openhardware.io i gonna upload it later tomorrow.
Thanks for the ideas, i will modify the code to use LowPower lib and will cut the power to the radio module to increase battery live, when last massage is send the node will never power the radio module, will be only short interrupt and go again to sleep forever. This will give me power usage 20times more than self battery discharge. Which have to give me node uptime around 260days with coin cell battery.
Yes but in this case the last massage will be the same like the previous, only the battery level will be below some predefined value. i don't like this. I will think how to solve this.
Is exist something "last wish" in MySensors, when battery go below predefined level the device to send last massage to the GW and go sleep forever.
The idea is the controller/application to have information about the device and to be known this device is dead and need battery change.
Thanks for fast reply, actually 900nA is to big number and i prefer to use xxx_POWER_PIN to cut the power of the NRF module.
I am building switch powered with CR2032 battery and i want to extend battery live as much as possible, for a switch is not needed to keep radio alive, i need it ON only when transmit signal
Do you know how much will be power usage in transportDisable mode?
What will happen if i cut the power OFF of the radio after each transmission? is it needed to be initialize again before next transmission?
Hello,
Some ware in MySensors website have info how to combine 2 sketches, i think one Arduino can handle all your need.
Hello,
Even without capacitors work well, for all of my sensors. With the capacitor only the range is little bit increased.
The SMD version of the NRF module works only for some vendors, there exist different pinout of those NRF modules.
Also there have one issue with the design, the one of the mounting holes are not align to Arduino hole at the moment i work to fix this, after fixing the gerbers will be updated.
I don't like one think here in openhardware.io there haven't project versions and when some change is made cannot be visible as changed, if somebody had already download the gerber files, will have old version of them and is not be alerted for new design change.
