Hi,
I am using ADC without external reference and no analog input in order to measure the battery level with a timer (code at the end).
I am also reading several ports...
Hi,
I'm programming the nRF51822 and save some user data into the FLASH by using pstorage_update . It works fine if I set system off mode, and wake it up. I can read back...
Hi,
I have been using nRF51822 with my Android app using Android's Bluetooth Low-Energy APIs.
In order to get more details, I am currently working on integrating the Android...
I'm looking at interfacing a typical Wheatstone bridge sensor to the nRF51822 ADC. This particular sensor only requires a mA or two for excitation and the output fits within...
When use the "nRFBeacons" app to update the info on my beacon the following happens:
Go to update tab.
Select "Connect"
Press "SW2" on beacon and see the LED begin flashing...
I am using s110 and nrf51822. I've set up up a long characteristic of 154 bytes.
Sending between 1 and 154 bytes works as expected.
Sending 155 - 160 bytes gets rejected...
Hi,
I tested the nrf beacon application, it allows only the beacons with company identifier 0x0059 (nordic's id). But i need to modify it to support all the device, how...
Hi, I'm working on an extremely space-tight design and need some clarifications. It is an nRF52832 QFAA chip with a Johanson 2450AT18B100 chip antenna.
Up to this point...
Hi,
I would like to use higher dBi antenna instead of the DK pcb antenna. Can I say the pi-network before J1 (measurement point) probe is 50ohm? Hence I can just remove...
I am trying to control another BLE device with nRF52xx. For controlling the device I need a terminal for connecting, disconnecting and switching on & off a sensor. I have...
I am using NRF52DK and trying to debug an SPI transfer, using SEGGER_RTT.h to print. However, printing of the logs are not consistent. Some debug lines do no appear in the...
Hello,
The only semi-official information that I can find regarding the differences between PCA10040 1.1.0 and 1.1.1 DK boards is this post . It suggests that there are...
I recently ordered two NRF52840-PDK and a Segger J-Link Base to program/debug the boards.
Then I just read that the development kit have a J-Link OB included, or I could...
Hi.
I wonder that how to setting continuous modulated output mode for nRF24L01P.
I see Appendix C - Constant carrier wave output for testing in datasheet.
But there is...
I see in the SDK 13.0.0 release notes that the NFC type 4 library was updated to "production ready", but I couldn't find a summary of the changes made to the NFC Type 4 library...
So... As I understand it, micro-ECC is a free library that lets you create an ECC private key for signing the SecureDFU that Nordic is using.
The nrf52840 has Cryptocell...
I've put on the stock dfu/bootloader_secure on the nrf52 DK.
I've then create a distribution ZIP and upload a blinky app to the DK. That worked fine.
Then I compiled...
Hi,
I have problem with DFU for 51822xxAB witch has 128kB flash.
I use dual bank bootloader for nrf51422xxAC witch has 256kB flash memory within nrf51822xxAB.
Ofcourse...
I know this might be a dumb question to you all, I am first time doing this sort of work
How to connect Jlink to NRF52? I need to flash a custom built BLE board with new...
I'm running on a nrf51822 chip, using Keil and a JLink Segger programmer. I'm running on SDK 12.2.0 and I believe I was correct in choosing pca 10028 s130 but I'm not 100...
