Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

We have tried to modify the following 0x1UL to 0x0UL and looks...
Hi Sir, I am use Laird BL651 module, which use nRF52810. I am use nRF52 DK debug output (P19 and P20) connect to our board, but the nRFgo studio not able to detect device...
Hi Nordic,
A problem was found with the SDK15.2 write operation. If the write size is equal to 12000 bytes, the system will return an invalid operation length error.
But...
Hello. I am developing an Android app and Arduino BLE device that will need to work in a very population-dense environment. Think a very large music festival with thousands...
Hello All,
I am trying to interface an analog sensor with nrf52832, whose analog values have to be converted using SAADC and has to be sent over SPI to another chip. But...
I am working on a project where an nRF52 is a multi-role BLE device. It is an advertising Peripheral, to which smartphones can connect, and a Central which scans for and connects...
Help, I want to run NRF_LOG_ENABLED builds but occasionally I want the device to sleep for (many) minutes, so I wish to turn off the NRF_LOG_UART backend since it consumes...
I plan to test BLE and Zigbee communication range in multiprotocol examples.
And I haven't found how to configure Zigbee tx power.
Questions:
1. Is the tx power of BLE...
Hi all,
I am trying to interface HI-3585 with nrf52832 through SPI which works fine. Now i have merged the code with saadc program so as to transmit adc values through HI...
Hello.
I am building nRF Mesh SDK using cmake (gcc).
After successful building the code, I flashed hex file to nRF 52 DK.
I want to know free space in DK after flashing...
We want to use nRF52840 as advanced USB - UART converter to control end device (see structure below).
We already checked that our end device is working fine by external...
