Hello!
How can I communicate with my nRF24L01+ and nRF51822 at the same time. I can set up same channel, CRC-mode and I don't use ESB. But what about address? How do I set...
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

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...

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,
