Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...

Hi all,
I am try to test light switch server example in mesh SDK (v3.2.0) with nRF5 SDKs(v15.3.0). Using Coded PHY(125kbps) as this post or standard PHY (1Mbps) seperately...
Hi Devzone!
I'm using the fft function to check the frequency of sound from mic sensor.
All seems good but, o nly up to 2500hz is shown and the frequency above it is...
Hello,
I am trying to measure the battery voltage on an nRF52840 DK using SDK 15.3, while consuming as little power as possible, so by using nrfx_saadc_sample_convert()...
The example initializes the SAADC driver and configures one channel to sample analog input 0 (GPIO pin 2).
I would like to know how to change analog input pin to other GPIOs...

Hi all,
My project involves a ble-central initialising peripherals and creating a bond. When this is complete the peripheral should go into sleep mode and only wake up when...
Hi Everyone!
I checked this links https://infocenter.nordicsemi.com/pdf/nRF9160_DK_User_Guide_v0.9.pdf#page=20 and https://github.com/NordicPlayground/fw-nrfconnect-zephyr...
Can we enable more than 8 GPIO interrupts? It seems like GPIO_MAX_CHANNELS is 8 but we need more than 8 interrupts in our application.
How do we do this?
Hello everyone, I have an external board with processor nrf51422 and sensor BNO055 (I2C). I have a processor code created by someone else and I have a problem getting data...
Hi,
I see there is a differenece between v1.0.0 and v1.1.0 in the asset tracrker's main loop.
i.e. poll function vs the sleep function.
does this result in a change...
Hi,
I'm working on a custom bootloader which does DFU over I2C. As a fail safe mechanism I want to have a timer running that gets reset between each Image data block, so...
When using SDK v13's I2S driver, the data to send is filled via data_handler callback. How do I fill last block data?
