Hi,
I am using the NRF8001 in UART mode and attempting to bond with my android device (Lollipop 5.0 Nexus 6).
i am using the nordic arduino sdk which is found here:...
Hi, I'm using the nRF8001 in an application that requires security so bonds to the remote client/central. My device supports firmware upgrades that may involve new nRF8001...
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.

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...
I would like to learn more about when it is safe to invoke soft device methods and when it is not. For example, are the following 'allowed' to make soft device calls to update...
Update to below: I get data out of the VCP and into Termite for a sub-second when I first power the board (with handshaking enabled), then I get no subsequent data (even though...
Hi,
I have just received a bunch of N550 modules and now I want to try and see if it is possible to update the firmware of these devices without using a JTAG.
If I understand...
I wrote my own ACI interfacing code, so I have questions about some details of the data credit system that most devs may be insulated from by the Nordic SDK.

Hi All,
I was wondering if it was possible to program the nrf51x22 in c++? I am using Keil and I'm trying to convert the examples in the SDK to CPP by adding --cpp to the...
hi,
I have used sd_flash_write() in my code. The scenario is that sd_flash_write() will be called after a DISCONNECT event. And it would wait for system events :

Can anybody shed some light on...
IUsing the Master Control Panel application on my Android device to connect to my nRF51822 module (acting as the GATT server), I have implemented the Device Manager (v10 SDK...
Hello all, to optimize the BOM and size of our device(Tag based on nRF51822), the external divider was replaced by software configuration to measure the battery voltage. In...
Hello,
I have seen, that the BLE MAC is increased by one, in dfu_transport_update_start() (dfu_transport_ble.c).
Can someone give me a short explanation, why this is done...
I have successfully compiled BLE application using tutorials provided on nordic website.
