• Tx current consumption_nRF51 vs nRF52

    Hi, The current consumption of nRF51822 and nRF52832 listed in the specifications are shown in the figure. The figure shows the current value of LDO mode. The consumption current of nRF52 is larger than that of nRF51. Could you tell us the reason…
  • Nrf51822 consumes more than 1 mA, How can we reduce it?

    My code is in the link attached: github.com/.../master With that code we have a current measurement of 1.1mA. As you can see in the code, we have tried to disable all the peripherals in the function: disable_peripherals(), and configure Advertising…

    Hi, I am testing the current comsumption of nRF52832 using the original code of "nRF5_SDK_13.0.0_04a0bfd\examples\ble_peripheral\ble_app_beacon ". The peak TX current I measured was about 12.5mA. It doesn't match the results in devzone.nordicsemi.com…
  • nRF52832 high current with __WFE();

    While analyzing the current consumption of my nRF52832 Dev Kit I noticed that the system on low power current was significantly higher than expected. To further investigate this I loaded a small program that only has a call to __WFE() in a while loop…

  • Help me understanding theorical power consumption of nRF52832

    Hello, We've been struggling for a while trying to understand how to interpret the nRF52832 electrical specification . Sorry if this may sound like a bad question but we really have to make sure we consider the correct values. Based on the electrical…
  • nRF51822 current consumption after power-up is often 1000 x higher

    We have been suffering about this problem quite a long time, maybe since the beginning of starting to use nRF51822 roughly two years ago. The thing is that we cannot trust that the nRF51 consumes only a few microampers after it is powered up. In a…

    Bonding causes power consumption to rise. I have a central and peripheral device communicating using the nus-service. The peripheral device is running FreeRTOS with tickless idle. When the peripheral device is advertising or connected to the central…
  • Disabling SAADC nrf52832

    Hi, I'm using nrf52 dk(PCA10040). I want to disable the SAADC between readings to save power. I am calling the function nrf_saadc_disable() to do so. It seems to disable it, but unfortunately when i mesure the power consumption it constantly draw 2mA…
  • How much current consumption when we use internal 32k RC ?

    I use the nRF52832 IC of WLCSP package. In addition, it sets as follows: {.source = NRF_CLOCK_LF_SRC_RC, \ .rc_ctiv = 16, \ .rc_temp_ctiv = 2, \ .xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_250_PPM} How much current consumption increases…
  • Current spikes when DCDC is on

    Hi, I use the nrf52 dk(PCA10040). When monitoring the current consumption of the advertising with the DCDC enabled, we see some current spikes. Why? Here is two screenshot, one with the dcdc enabled and the other with the dcdc disabled:
  • Adc consumption

    Hello all, I am trying to activate ADC to measure a voltage every few seconds using nrf51822. When it is done, I supposedly deactivate ADC so it does not consumes while I don't need it. I find that the consumption increases when I activate the ADC…
  • What is the current consumption between advertisements on the nRF51422 and nRF52832

    According to the product specification of the nRF51422 the current between the advertisements is: i_sleep = I_on + I_rtc + I_x32k 16k Ram enabled: = 2,6 µA + 0,1 µA + 0,25 µA = 3,1 µA 32k Ram enabled: = 3,8 µA + 0,1 µA + 0,25 µA = 4,3 µA for…

  • Tx current of nrf51

    In the datasheet it is mentioned that the tx current is 10mA without DCDC. In our board, we are seeing a Tx peak current of 13.5mA. So my question is the does that quoted 10mA tx current include the 4mA current consumption by the ARM core, so that overall…
