Hi, For a node I’m developing at the moment, I using a power-gating MOSFET from a nano current timer (tpl5111)to switch my entire node off. This is an extremely elegant solution as it allows me to run ultra low current (35nA). But I just recently came across OTAA best practice and saw that the join…

Once you are under 1µA, the real factor in power consumption is the awake time, not the sleep time… If you draw 1µA in sleep time, it will require a capacity of 10 mAh over a year, which is nothing compared to the wake-up current draw. To give an idea I measure 0.84µA on my nodes, with RFM95 and B…

[image] samisabik: This is an extremely elegant solution as it allows me to run ultra low current (35nA). It might seem that way, but in practice, perhaps not. It depends on the exact circuit of course, but an ATMega328 and LoRa device is capable of a deep sleep current of circa 1.5uA. A sl…

Thank you for your answer; I am indeed re-considering the power gating option. Initially I was using ABP, therefore the issue never surfaced with the JOIN. But yes, I think using the TPL5010 on a hardware interrupt to wake up the MCU seems the best case scenario.

What method would you recommend for deepsleep? External interrupt from RTC or nano timer LowPower.powerDown(SLEEP_8S, ADC_OFF, BOD_OFF); looped as many time as it’s need to reach 2h.

There are some notes on power down versus deep sleep in the section entitled; “Reducing Tracker node sleep current - a wasteful race to the bottom ?” In this report; [image] LoRaTracker/GPSTutorial A simple tutorial for troubleshooting GPSs on Arduino - LoRaTracker/GPSTutorial …

How to get dev_EUI from RFM95 with arduino nano? I have problems Thanks in advance.

@am1lcarcaceres just let TTN generate you a unique one when you register a device

[image] am1lcarcaceres: How to get dev_EUI from RFM95 with arduino nano? I have problems The RFM95 does not have an EUI so you will not be able to get it. Use a TTN generated one like @Paul_Stewart suggests. Which library are you using to drive the RFM95?
