We would like to be able to calibrate the rRF9E5 ADC
Our proposal is to permanently fit voltage dividers, each using two precision resistors, on two of the ADC Ports and...
At some point in the past I had nrf51+gdb+breakpoints working just fine. I even have a bunch of __BKPT() calls in my various error handlers to trap into the debugger.
At...
Hi,
I'm trying to program nRF51822 Beacon Kit using nRF51DK. I'm trying to load the example ble_app_beacon to the beacon kit. After uploading SoftDevice 7.1.0, I try to...
Hello
I'm using the nRF51 DK and I have a UART over BLE link set up between the board and a phone with the nRF UART app. I'm trying to get the board to execute a particular...
Hello there guys i been reading your 100 pg PDF for awhile now and im yet to understand or realize how is it that i add/place/create a payload or data to send/Tx via Master...
I am interested in writing a BLE central that reads data from multiple BLE Nordic sensors. The BLE central will be running on Embedded Linux which uses the BlueZ stack.

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...
at nRF51 SDK v9.0.0, S130, PCA10040, at peripheral side
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'm using Eclipse Mars 5.2 on Windows 10 along with the GNU Toolchain as described in the "Development with GCC and Eclipse Tutorial" by Vidar Berg (Thanks very much...
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...
In the picture, the usb pcb is PCA10000, the circle PCB is the product PCB.
The diameter is 20mm.
Chip antenna is used now but the distance is 5m in 4dbm TX.
