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.
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...
I'm trying to implement a burst transfer between to nRF24AP2 devices, but I have serious problems getting it to work.
The burst messages are send on a reverse channel to...
Hi, I need to read an analog signal 100 s/s which takes 68us at 10bit. There is very little computation to be done once read probably about 10us which I can do to the previous...
I am experimenting with calling sd_flash_write with waiting,
if it returns NRF_ERROR_BUSY, just try again, and then return either success fail
void flashWrite( uint8_t...
Hey ho,
I'm new to BLE and Nordic. I'm a student from Germany and i want to realize one simple function with Arduino (RedBear Blend with nRF8001) and Android.
I want my...
Hello,
We've heard that the BLE transmission packet length may be increased beyond the limit of 20 bytes in a future version of the S110 softdevice. Would you let us know...
Hi
I struggle to understand mechanisms of switching particular subsystem of nrf51822 off and on again in order to consume as little as possible current when MCU is put...
Hi
I have an ADC that just recive, but i will need to make an buffer that makes tx values and just send them to a output pin.
So I wonder how i should code this and if...
I have made custom compiling environment using gcc. I precompile some parts of my software and send to team members .o files what they use in their project so that they don...
Hi, I am using an nRF51822 EK board to develop a custom application and I was wondering about the usage of the SoftDevice. Under what conditions should I use the soft device...
I have recently updated my DFU code to use the source files in SDK 6.1 to be able to OTA upgrade the SoftDevice and Bootloader. I've been able to get the Application to reliably...
Hi,
I am a newbie and would like to build a solution that combines nrf51822 with Arduino. Is this possible.
I find that there are many nrf5001 + Arduino solutions, but...
Hi,
I try to use APP_ERROR_HANDLER(err_code) with a custom error code ( for example 25) in a custom function. Error code reported is correct, but error line and filename...
hello,
Have any example about how to use "CHANNEL_IN_WRONG_STATE" ?
I don't know how to use it. and also don't know when softdevice return this even.
