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…
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 measured the current consumption of nRF52DK with the original code of "nRF5_SDK_13.0.0_04a0bfd\examples\ble_peripheral\ble_app_beacon ",
based on the current measurement guidelines.
The results is that the current in the system on idle mode is…
Hi,
I want to reduce the current both in the TX mode
and in the system on idle mode as much as possible.
I measured the current consumption of nRF52DK with the original code of "nRF5_SDK_13.0.0_04a0bfd\examples\ble_peripheral\ble_app_beacon ".
THe…
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…
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…
I am developing a battery powered application using the Nordic UART Service.I intend to use the ble_uart peripheral example as it is , modifying it as per the application.The peripheral is battery powered and has to do both receive & transmit tasks intermittently…
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…
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…
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…
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…
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:
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…
I have following set up for current measurement.
NRF52 DK PCA10040 v0.9.0
nRF5 SDK v11.0.0 : Power Profiling Application
S132 SoftDevice v2.0.0
nFR Master Control Panel Android APP
Keysight N6705B
I have flashed the default application…
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…
First of all I'm a BLE novice, so sorry if I'm asking obvious questions. I've built a home project where a battery powered mcu listens for requests over wifi and drives a couple of solid state relays. It works but power consumption is being an issue,…
Hello there,
I'm currently using nrf52832 with s132 and sdk 0.9.2, based on the 'ble_app_uart' example and keil5. I'm concerned about the current consumption because in IDLE mode I should expect very low current consumption(~2.5[ua]) while reading…
Hello,
I found this on the forum:
According to nRF51822 PS v3.1 section 8.23 pullup and pulldown resistors have a typical value of 13kohm. if you have e.g. a button that connects a certain pin to ground when pressed, and the pin is configured…
I'm had develloped some software and tested it on the nRF51-DK.
After that I made my own PCB design where only the nRF51422 is replaced by a nRF51822.
When I flash both with exactly the same software, the nRF51-DK consumes about 5.6uA and my own PCB…
Hello,
I am working with nRF51422 & would like to know if I can measure current of single event & multiple events (pictures attached) as detailed as possible. I have cut SB9, mounted 10ohm resistor for R6 & connected probs on Oscilloscope as mentioned…
I downloaded the power consumption example code to a nRF51-DK to measure the current consumption during SYSTEM ON and SYSTEM OFF state.
For the SYSTEM ON state, I used the "system-on-wakeup-on-rtc" code. The current consumption was 4.4 mA and 1.2 mA…
