Hello:
I used analog IIC write MPU6050. Again after power download programs, mpu6050 can run up there ACK response. But the debug will not run. Simulation IIC because no...
I'm trying to write a central BLE with the dongle(PCA1000) using s120.
I programmed s120 sd ver 1.0 the same way as the s110 with the nrFGO ver 1.17.
However i keep getting...
Hi all,
I need to change the device name frequently to show button status.
So remote device can see button status without connecting to device.
Is there any way to...
Hi guys,
i have a service with more characteristics and more states. Not every characteristic should be available in each state. Thus there are services which are just...
Using the S120 soft-device in the Central role, there does not appear to be an
example or documentation describing how to scan for a 128 bit UUID service.
Has anyone tried...
Apparently there is some limitation on length of the paths with Keil. The paths are specified under "Options for Target" --> C/C++ --> "Include Paths". Due to this limitation...
I downloaded the nrfgo Sdk for the nrf24lu and nrf24le. In the projects folder there are several examples, two of which are of interest. The first is entitled "bootloader_32K...

I'm done with the hardware interface of my current project.
Right now I have a service running with a custom UUID, by writting this characterisitics you have access...
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,
i need to save an array of 50 kB on the nrf51822 flash. I only need to read the data stored in the array. I come from the PIC micro world where i simply need to initialize...
