I know that suggested debugger for nRF51xxx is J-Link or openOCD with CMSIS-DAP, but I would like to use BDI3000 debugger, which does support SWD interface and Cortex-M0 processors...
Hello. I am literally looking at the set_hrm_cccd function in Python used to write data. This is for the S130 heart rate collector example. I understand the sd.ble_gattc_write...
Totally new to Python but managed to get things like pyserial setup and I've been able run the ble sniffer. However that is as far as my Python knowledge extends, so I need...
pstorage_load and pstorage_clear appear to work fine, but whenever I do a pstorage_store the callback function is never called. This happens whether or not the Bluetooth unit...

In my design I need the RX to be standalone , I.E. no controller attached to it , does the programming STORE in the Chip ? If I set it up as a RX and set a specific Ch. Freq...
I have programmed nrf51-dk with an example code available at mbed platform,everything works fine except that the ble is visible even if we open bluetooth menu.It is scanned...
Hi,
I'm developing something with NFC / BLE handover - it is currently working fine, NFC tag is read by a phone, nrf52 starts advertising and phone then connects to it over...
Hello,
I'm remaking an nrf52 project in Keil and ran into an issue when it came to compiling. All of the errors outputted have came from bsp.c, mostly stating that a few...
Hi,
We will use nRF52 along with small 8bit micro and UART connection. The MCU cannot support standard baudrate 115200, and we will need to implement non-standard speed...

I have been working on a project that involves two nrf51 dev boards, one is acting as a central and the other is acting as a peripheral, and I have been encountering a problem...
Hello!
For beginning with nRF51 I chose BLE Nano set of boards (BLE Nano + MK20 USB donbgle) and it was of great help to easily begin with BLE.
So far, we came to the need...
As an experiment, we want to implement soft power off for nRF52 with external components. We want to keep the entire circuitry entirely switched off, and after a press of...
I do not use board.h nor bsp* in my project, and also I am not initializing the pins that I do not use in my program currently - so P0.17 is not initialized and setup. However...
