Hi,
I'm having the purpose to use nRF51422 /ANT to connect a relatively data hungry ANT device. The nRf51422 specs expose three programmatically available data rates : 250...
Hi,
I've written a nRF51 SWD-JTAG programmer.
I want to enable it to check for minimum softdevice version and error out if a too-old softdevice is found.
It is easy...
I want to communicate four same devices with different hosts. i know that one host can communicate to seven devices and also a device is able to speak different hosts . i...
Thanks for the response. As a test, I loaded the same code onto a PCA10004 and it seems to work as you described. A breakpoint at 217 does get triggered when it receives data...
I have been perusing the source to micro-esb, and it appears that it wants exclusive access to the NRF_RADIO interrupt(RADIO_IRQHandler) and things are designed so that only...
Hi,

On centrasl side is S130. After discovering services i enable...
I want to use the pca10001 to communicate as a master to an accelerometer, but when i use the function spi_master_open i get a NRF_ERROR_NOT_SUPPORTED error. I get no clock...
Hi everyone.
I am working with nRF51 to make two BLE device, One act as cetral and another as peripheral.
I have implemented almost functions that the two devices are...
Hi,
Do all NRF51822-DK (development kit) have the same silicon build revision? If not, which distributor should I approach for the latest revision and is there a specific...
I have encountered a problem with the IAR linker where I run into a 32k code-limitaion, even though I have a licence with no limitations. According to IAR, the problem may...
I was playing around with examples and decided to implement a custom service that sends the RSSI as a single-byte characteristic value. Here's the init function:
static...

The following code gives me error 3003 which I figured...
Hi,
I think getting started with the Nordic chips is not as easy as some others.
I would like to know what are the first things that I need to run my code on a Nordic? Especially...
