Using one ADC, the current can be reduced to about 40uA after the ADC value is taken. Using a two-channel ADC, after the ADC value is taken, the current stops at about 0.4...
I'm searching for a software engineer who can help us getting OTA support between nRF52810 and PIC16 MCU.
nRF52810 must have command- and data mode over UART, Pic controler...
I want to be able to read the gyro and accelerometer values from the MPU6050 sensor.
As a base start I downloaded the NRF5 SDK V15.3.0 and modified twi_sensor_pca10056 program...
Hi. I'm using nRF52832, SDK13.0.0.
I should use SHA256 and MD5.
I made my code as below.

Hi there.
I'd like to start measuring the current consumed by a custom board with an nRF51822 on it in various states using a scope. I've read the DK user guide advice...
Hi,
We've developed a prototype for a client and just received the nRF51 chips for production. Problem is that the chips that just arrived is an older revision than the...

Hi all,
I'm having a tight deadline upcoming and have run into an anoying problem.
I'm using this NRF51 breakout board: ohtcom.com/.../nrf51-m0-module
I ordered a...
HI I am trying to make 5 characteristics on Nordic and my program does not compile for NRF51822 QF AA or AB. but compiles fine for QF AC. what could be the matter. I get an...
Hi,
At command, I'm sampling ADC for a short period of time. What I noticed is that the current consumption of the chip goes up 2mA, even after the sampling is stopped...
Hi,
What is the actual difference in hardware between the two chips? I know they support different soft devices but is there any actual difference in the hardware? Or is...
Does having monitor mode debugging or using RTT print statements increase the quiescent current of the nRF52 even when the debugger isn't connected? I am using S132 SoftDevice...
I'm in the process of porting code from a PCA10000 rev2 board to a custom board, using the ISP130301 integrated MCU (contains a rev3 nrf51822 IC). I'm using nrf51 SDK 6.1...
Hi,
I use an nRF51822 QFAC A1 and my goal is to disable BLE in a powerdown mode, then when I press the pushbutton I want to restart BLE.
Tried using BLEDevice::shutdown...
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...
Hi,
I am having some trouble to make NFC Tag emulation working with "ble_app_hrs_rscs_relay" example application in the nRF5 SDK v11.0 on a PCA10040 board. Actually I did...
Hi all,
i have a little problem with the #define NRF_LOG.
I have this warnings, and i don't know why.
