Hello, How is your current consumption in standby mode using LMIC library ? I am testing with a whisper node and I measure around 90uA. I am using a multimeter to take the measurement for the lack of a better measuring equipment. While testing with a script provided by the maker I measure around …

I have here a Sensebender on 23uA. [20180618_213452]

Thanks that helped setting some expectations. I reconfigured everything from scratch and after lots of testing I get the same measurements as you so I think I am good. I must have misconfigured the temp sensor and I was wasting excessive battery I am using the bme280 in standby as well and it seem…

I’m around 2.4 uA on a 3V battery powered device based on a STM32L4 MCU and a NiceRF frontend. I’m putting the MCU into stop mode but I’m pretty sure I could lower that consumption if I start playing with standby or shutdown modes.

[image] Full Arduino Mini LoraWAN below 1uA Sleep Mode End Devices (Nodes) Hi Guys, I’d like to introduce my new demo node, no wire, just battery powered, Arduino Mini 3.3V 8Mhz. I created a demo for a customer with a fully Temperature Humidity sensor (I2C SI7021) with Ba…

[image] cgeorgia: How is your current consumption in standby mode using LMIC library ? LMiC has no knowledge of how to put an MCU’s core or peripherals into a low power mode. That is really up to whatever “glue” you use to adapt LMiC to your hardware. LMiC’s scheduling mechanism while perha…

Hello, I am running LMIC on the classic Arduino Pro Mini / RFM95 combination. To reduce the power consumption during passive mode LED’s and voltage regulator are removed and the sensors are shut off. But… I think in active mode you can also reduce some power. First to disable the bootloader and sec…

[image] Wijnand: But… I think in active mode you can also reduce some power. First to disable the bootloader An ATmega bootloader has no impact on power consumption once control is transferred to the main program / sketch. At that point the bootloader no longer has any role in operating the …

[image] cslorabox: An ATmega bootloader has no impact on power consumption once control is transferred to the main program / sketch. If you use (deep)sleep mode, OK. But if you shut down the power supply completely, it has to boot every time. [image] cslorabox: It’s possible to disable r…

I found the “Adafruit TinyLoRa” discussion, thanks…

[image] Wijnand: If you use (deep)sleep mode, OK. But if you shut down the power supply completely, it has to boot every time. Without the bootloader, you save about 1.4 seconds of runtime.
