I'm using 51822 QFAC, SDK11 S130 2.0.0.
I'm able to write to flash using fstorage_write() below. But the problem is whenever I put a for loop after I call fstorage_write...
Hi,
I built a simple custom board with an nRF52832 ebyte BLE module with no added components except for the RST and DFU buttons, the serial wiring are the same pins (RX...
Hi,
I'm working on a BLE scanner which need collect data from the beacon's scan response packet.
As far as I test, the current mesh beaconing example cannot get the scan...
I plan to use nrf52840 in high voltage mode (connected directly to the power source via VDDH pin) with button.
And I plan to use voltage regulator with EN pin (with pull...
The most relevant thread on this topic is two years old. I do not want to use Keil as it is so costly and the project may not go anywhere. I am not interesting in using the...
Is it possible for me to easily modify the nrf52 Zigbee samples to run on 1 or more of my 5340 M33 cores, or is it a rewrite?
I can see chip support for nrf52 but no mention...
Hello,
We recently sent a design to our board assembly house for review and they indicated that the large copper area under the nRF528323-CIAA (WLCSP) may result in head...
I’m using nRF52810 on a custom board (for our own application) using SDK 15.2.0 v6.1.0 S112. Given the amount of memory this chip has (192/24 KB) is it possible to implement...
I'm using the nRF52 DevKit with nrf52832 SoC. I connected a UV Sensor through the TWI interface (PINS 26 & 27, as well VDD and GND).
However, I fear it's using a lot of...
Hello,
Till now I was using nRF52840 with nRF5_SDK_16.0.0_98a08e2 and its working fine. Now I thought to cross check with nRF52832.
When I run FDS example I am getting...
I have been studying the power consumption of a prototype and observe that the end device is polling very frequently. The data request polling is backing off for a while to...
I've been observing a strange behaviour on the MOSI line using SPI2 in Mode 0(nRF52832) with connected ST7789 based display,
The data happens to be not available at the...
Dear Nordic support team,
I am developing a prototype based on the nRF52840 with the nRF5 SDK 16.0.0 and Soft Device S140 7.0.1. The prototype acts in the peripheral role...
