I'm trying to use the ADC and internal reference to measure battery voltage on the nrf51422, while S210 is enabled.
From the example nrf51-ble-app-temp-master, I found...
I have Nokia Lumia 630 and it works well with nRF51822-EK but only with SDK nrf51822_v5.1.0.36092 and SoftDevice 6.0.0. Now I decided to try DFU OTA. I programmed bootloader...
Hello,
I found that there is a multiprotocol demo in folder Board\nrf6310\s110\experimental\ble_app_multiactivity_beacon,then I found it can implement concurrent connected...
Dear Sir
We got the problem on DFU upload firmware, it always failed in second DFU . We must unpair the device at iOS setting panel. Before next DFU.
Here is the log data...
Hi All,
My requirement is to read the data from nRF51822 device that is connected to a bluetooth and bluetooth is connected to a system using a .Net application.
I have...
Hi everyone,
I'm using the nRF51822 (pca10000 Dongle + pca10005).
My plan is to send one byte over the radio.
I tried to use the SDK-Example as a template but it's...
Hi,
Is that possible to run the radio_test_example (\nRF51 SDK_v5.2.0.39364\Nordic\nrf51822\Board\nrf6310\radio_test_example) on the nRF51822EK? If yes, what modifications...
I've recently discovered the power consumption issue with FreeRTOS and SDK12.3:
devzone.nordicsemi.com/.../
So, I am now using SDK12.3 with SDK13.1 FreeRTOS files.

I am using Nordic SDK to program an nRF51822 chip. I want to optimize power consumption as much as possible so I am looking at using the -march gcc flag. The problem is I...
I am using the ble_peripheral template that comes in Nordic SDK 8.1. I setup uart logging and also debugging with the following lines of code:
void assert_nrf_callback...
Hi, We are trying to connect a LED to one of the GPIO of nRF52840, we would like to know how to connect it. Connect it such that the nRF52 GPIO sink current or source current...
Hey, I am using WT51822-S4AT module and want the nrf51822 to connect to phone. I don't have nrf51-dk. I am using stm32f0-discovery kit. Can it be done using that kit? I searched...
Seems battery reads are not consistent in thngy52 2.1.0 software.
Observed a ~4% difference in the consequent battery reads. This difference is high (upto ~40%) if the thingy...
In the recent past, I used a SoC in which GPIOs could be configured as "open drain", that is in which there is an internal transistor where the SOURCE is grounded, the DRAIN...
Hey,
I'm using nRF as a SPI slave with a Raspberry Pi. I'm seeing that even at ~3MHz SPI frequency, my first byte transferred gets corrupted. I have a test setup where...
I am using nrf52 with s132 and armgcc
As I add functionality to the code I get to a stage where it fails. Linker runs OK but the result fails to execute.
The observable...
I am currently working on a BLE beacon project on nRF51822. Using SDK 12.3.0 and s130. The device has to advertise URL, advertising name and output power level. And these...
I am trying to control a current measurement chip (DDC114) that works with a protocol that is close (enough) to SPI. It has 2 channels, s.t. it can be read out and integrating...
I am attempting to run my first bit of code on my Nordic nRF52-DK and every time I have attempted to upload the code to the board, the board disconnects in the middle of the...
Hi, I'm using nRF52832, SDK13.0.0 as peripheral.
My iPhone app(my company's) makes connection without problem.
But Android app gets connection fail when it tries to connect...
