Hi devs,
I am working in an nRF52 DK.
The attached example is not working when I change the SCL and SDA pins of TWI1 module. This is also not working if I disable TWI1...
Hi,
Is there any software I2c library or example projects for nRF52 devices (PCA10400) with pin configuration, read and write functions? I am using an SMBus based sensor...
Hello,
I am testing the ble_peripheral example of ble_app_uart (SDK 12, soft device 130), this has been asked at a lot of places that the MTU is limited to 20.
But then...
Hi,
I am using nRF51822 and implemented timer-2 with 2 sec capture/compare interrupt rate. But if I want to read timer's current count before it generates interrupt or...

If we receive a characteristics less than 20 bytes, we can get the correct handle value(like 0x3B). And then everything...
I bought nRF51-DK yesterday.
I installed nRFgo Studio(1.20), Keil uVision(5.15), Softdevice s110 (8.0.0), J-Link(5.00),
nRF51 MDK(7.2.1)
I turned on the nRFgo studio...

Hi, I can't get SPI slave mode working on nRF51822. I'm using the Core51822 module with a BLE400 board from Waveshare and up to date mbed. SPISlave::receive() always returns...
I implement it with sdk 11.0 and a third party core-board.Firstly,I program s132_nrf52_2.0.1 SoftDevice by nRFgo Studio,then I open ble_app_hrs s132_with_dfu(arm4) project...
Hi,
Currently I'm using internal RC osciallator for LFCLK on the system that run on CMSIS-RTX and Softdevice S110 and it doesn't have external 32K crystal.
The RTC os...
Hello,
I just received an NRF52DK today. I was able to run the demo (LED blink/Switch and NFC) which comes factory installed. But copying the hex files from demo (proximity...
