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...

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...
Hello,

calculating the time elapsed between parts of the...
Hi!
Does anyone run UARTE with EasyDMA enabled? I don't want to use interrupts and simply copy every received UARTE bytes to global tx_buffer....and pooling with amount...
Hi,
I want to produce a shared secret key between a Smartphone and a NRF52 in order to encrypt data later with AES-128 (example of key sharing: here ).
To do that i need...
Been having a bit of trouble porting our nRF51 project to nRF52 SDK11. It seems to not like using hal_cm4.c from RTX_CM4.lib with FPU. Seems to get stuck on OS_Tick_Handler...
HI，I want to store some data in 51822. These data was store by my program. I know the pstorage.c could store data. When I do DUF the data could be erased by the bootloader...
I am interested in optimising inputs for ADC measurement on an nRF52.
I have seen quite a bit about nRF51 but am unsure if this remains relevant for nRF52?
Hi!
I have an nRF52832 on a custom board. I managed to flash it through JLink and STLinkv2. But suddenly, I wasn't able to communicate to it anymore.
Openocd tells me...
Hi
The new signed DFU in the SDK12.1 comes along with a experimental buttonless DFU. There are a few bugfixes required to make it working, but the nRF Toolbox app didn...
Hi:
Recently, I want to use nRF52 to read or write some data from a flash chip(w25q128bv) by using spi, I've read Manufactures ID correctly, also, I have wrote a register...
Hello!
I need to interact with two J-Link debuggers, connected to the same PC at the same time. I would then read and write data to the devices connected to the debuggers...
