Hi,
I have two CPU in our product. (STM32F2 and Nordic nrf51422).
I use serialization function to link those two CPU(refer to ble_s110_serialization sample)
But I find...
I have a question on - to me - seemingly weird behavior about copying data out of the event from the soft device.
Situation: I have a 32 bit integer characteristic which...
Hey all!
Newbie here. I developed and tested some code on an NRF51DK easily enough using mbed, and now I'm trying to put it onto a PTR5518 module from Xuntong (which I...
Could you rub my nose in Bluetooth SIG Core or just explain what does chip do when switching to very noisy channel? For example Wi-Fi working very close to our device.
Hello:
I have read the documentation but I cannot determine if INPTR and OUTPTR can be set to the same memory address? I will try it to see what happens but it would be...
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 everybody
I am making a custom board which using ANCS (nrf51 sdk 9.0.0, softdevice 110 ver8.0.0). I saw on the original code have button_led_init() function to initiate...
hello,
I've encountered a problem with our own nrf51822 circuit not advertising.
Our circuit is exactly the same as what is given as the reference circuitry on the datasheet...
It's the first time i'm using the spi to connect various slaves, so is there any example how to communicate a raspberry with 2 or more nRF24L01 on the same bus?
Thanks in...
Today I have recieved the new nRF52 Development kit PCA10040. I did a update for the nRFgo Studio to version 1.21.2.3.
The softdevice s132_nrf52_2.0.0 will be flashed without...
