Please,
It seems that "Flow Control" signal is not available on nRF24AP2-USB.
EVENT_TRANSFER_TX_START event message appears only one time after the first data packets...
I am looking for cheapest (up to few hundred USD) and simplest Arduino basic solution to track real-time RFID tags distance (also direction if possible) without additional...
Hi all,
I am new to Nordic semiconductor but I could be interessed by nRF9E5. To check if it could fit my requierement, I would like to know if it possible to configure...
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...
The GCC linker scripts included with the nRF51822 SDK (checked: 6.0.0 and 6.1.0 as well as nrf51-pure-gcc-setup ) include .init_array sections , but do not specify them as...
Why does the soft device raise a SWI2 interrupt to indicate to the application that an event occurred? In the SDK, callbacks are implemented using function pointers. A function...
Hi!
I'm launching code from example to NUS (ble_app_uart) on nRF52-DK. Everything is going OK, except when I quickly send 4 packets in row from UART to connected Bluetooth...
Hi,
I'm currently working on the project with some hard-timing dependent features. As I've mentioned in another topic, it fails if I have advertising turned on. Turning...
Hi, after I updated my MAC OS X to the latest version EI Capitan, I found my JLink commander cannot connect to the PCA10001 board again even with the Jlink commander updated...
I read somewhere that to get the callback working on pstorage write, read etc, you need to call pstorage_sys_event_handler() in a function set by softdevice_sys_evt_handler_set...
Hi,
Each Gazell device has unique address identifier (i.e. base address + prefix) mapped for each pipe. How about the host?
For example:
Device that transmits on pipe...
Hi,
Each Gazell Device has an unique address identifier (base address + prefixes), what is the default address identifier for the HOST?
For example
Gazell device transmits...
Hi,
I'm having trouble with how to begin debugging a hard fault error in my code. When I run the debugger, it always ends in the HardFault_Handler in arm_startup_nrf51.s...
I am developing a project by employing nRF51822 and my code is based on ble_app_uart. I met an issue that if there is no device connects to nRF51800 in 3 minutes, the program...
The nrf51 ARM Cortex-M0 processors, according to the documentation, are "code compatible with Cortex-M3". Does this mean they implement LDREX/STREX instructions for atomic...
Hei,
We would be using nrf52 chip in a very miniature device that should have both BLE and NFC capability. NFC is needed for just as a tag. Thus, nrf52 is a good option....
I moved from SDK 7 to SDK 9. I'm using timers with SDK7
APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_MAX_TIMERS, APP_TIMER_OP_QUEUE_SIZE, true);
err_code = app_timer_create...
I work with the IAR Workbench and the nRF52 and would like to enable the floating point unit. After installation of the MDK-8.1.0 and the check of the nrf52832_xxaa.i79 file...
