Hello, I'm working with the EK PCA10003, that has the NRF51422. I'm trying to read the information of the accelerometer MPU6000 with an ISP interface. At the moment I cannot...
I'd like to use the GATT/GAP driver from an ARM based Linux system. Is there any possibility of getting a library compiled for ARM or (cough) the source code to build it myself...
It is possible to run easily a SoftDevice stack (e.g. S110) on nRF51422 using an accurate 16MHz external clock reference for HFCLK instead of an external 16 MHz crystal oscillator...
I want to change data bytes in the advertisement packet. In ACI_DEVICE_STANDBY I put: lib_aci_open_adv_pipe(1);
In ACI_EVT_CMD_RSP: I get feedback that command 1B (I assume...

I have code for the SAADC based on the Low Power SAADC example here .
I have modified it to sample 4 inputs, and changed the...
Hi,
I would like to check battery level using the SAADC of the nrf52840.
Assuming the voltage is less than 3.6V, do I need to have a resistor between the battery and the...
HI,
I am new to IoS development with NRF.
I am having NRF52840 DK, IoS device. I want to implement USB HID device application (similar to pulse/Gluco meter ) on IOS. I...

Hi,
I am using fatfs of nRF5_SDK_15.0.0_a53641a.
I am writing a program with keil.
I am currently doing SPI communication with BLENanov2(nRF52832) and SD card with...
Hi,
I am implementing the UART on NRF52840. TX works but the RX doesnot. While debugging, I noticed that STARTRX task register is not getting set due to which the RXDRDY...
Hi Sir
We'd want to do RX testing with DTM mode, however, the dtm example code looks can't report receive data or total packets counts,
So that, we don't know how to determine...
Hello,
I'm using the nrf15822 chip and am using the ble_app_uart example from nrf5_sdk_12.2.0.
I know softdevice will automatically generate random numbers through RNG...
I've been told due to PAN 58 it is not possible to use EASY DMA with nrf52832 without switching to the deprecated SPI driver. Is there a workaround that allows the use of...
Hello,
We are going start custom PCB design by using nRF52840 chip and SDK 15.0, but confused for use 3rd party nRF52840 modules or design complete custom PCB using componenets...
Hi,
Despite knowing a fair bit of the theory of wireless comms (mainly PHY and MAC), I'm brand new to actual hardware configuration/protocol development, so please be gentle...
