Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

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.
...
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...
