I am designing an ultra-low-power BLE Audio TWS board based on the nRF5340 and have followed the recommended hardware design guidelines throughout the project. This is my...
Hello! We are in the middle of an upgrade to 3.2.1, and we encounter the following issue using SB_CONFIG_MCUBOOT_MODE_SWAP_WITHOUT_SCRATCH, SB_CONFIG_MCUBOOT_MODE_SWAP_USING_MOVE...
Hi everyone,
I'm using the nRF5340 on a custom PCB board without an external 32 kHz oscillator. On the network core I flashed the hci_ipc sample.
For some reason I occasionally...
Hello,
I am measuring RSSI values with nrf_modem_dect_phy_rssi(...) from the DECT PHY firmware.
The nrf_modem_dect_phy_rssi_event refers to positive values being saturated...
Hi all,
I'm working on BLE time synchronization between nodes using hardware timestamps via GRTC + DPPI + PPIB cross-domain. CRCOK and PHYEND work perfectly, but adding...
Nordic nRF51822 ARM Cortex-M0 Development using emIDE
To avoid the hefty charges with commercial compilers I tried emIDE with some success; here are the settings I used for the EV Kit
Official emIDE…
I connected the programming header as described in "nRF6930_Beacon_Ref_Design_UG_v1.0.pdf" 5.5.4 Programming interface. I was trying to program Beacon Kit but failed many times then I compared it with…
Hi,
I have written SD & SDHC card routine for reading, writing and erasing data from SD card. It used the hardware SPI of nRF51822.
NOTE:
1)Define the PINs of SD card first before initialing.
2)Define…
There are several types of write operations, write request with authorization, write request without authorization and write command. You can see message sequence charts for those messages here and he…
Here is an example of a hardware setup to measure the voltage on a Lithium battery with a voltage divider and a connected capacitor. The Lithium battery typically has a voltage range of 2.7 - 4.2 V and…
I've put up on Sourceforge, a Mac OSX application which interfaces with the Nordic BTLE sniffer software and has some of the functionality of the Windows application Nordic ships with that software package…
