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...

Hi all
I'm trying to build a generator based on NRF52832. Outpit signals are: 8MHz clock and two latches signals highly sinchronized with clock - RGB_LAT and TXT_LAT. For...
Hello,
I have a question on how to calculate the capacitance based on oscillator relaxation for NRF52. For example, in the Csense_drv example, when pin is touched by finger...
Hi,

Hi, I bought an Arduino PrimoCore card and I read that you need to buy the Alicepad card. I can not find it on the net. But was it put on the market? Thank you.
Hi,
I have added new UUID (Service and Characteristic) into the uuid_definitions.json but it's not used in the application.
To try I put a error into the json file and...
Initialization:
The softdevice is initialized as in the BLE UART example. The body of the ble_stack_init() function is identical to the BLE UART example.
SPI is initialized...
I have two supplier for provide me nrf52832's based modules.
So I tested it and both is ok. The distance used pcb antenna almost the same (about 80m).
If I use on external...
My application is built using the nRF52832 device.
The system must only be "active" between certain times (5am through to 9pm).
I am a newbie and have no idea how to set...
Hi,
what are the minimal required steps to get the zephyr HCI-UART on a PCA10040 working with Linux BlueZ?
The steps I have so far [My host is Ubuntu 17.04]:

Hello,
I am having troubles to run the light_switch example from the nrf5_SDK_for_Mesh_v0.10.0.
I am using PCA10028 boards with nRF51822. I didn't modify anything in...
I basically need clarification on the last point of this question , which seems to imply that:
the first time you call sd_ble_gatts_hvx() while the SoftDevice's transmit...
Hello,
the NFC library provided in SDK (nfc_t2t_lib_gcc.a) is compiled with the FPU support. For specific reasons, we can't currently use the FPU in our project. Would it...
