Hi,
I am trying to get the s130 example to work on my PCA10028 board nRF51.
First I had to change the starting adresse from 0x1C000 to 0x1D000.
I guess that this is due...

Is there a limit to the number of characteristics per (custom) service?
After some testing, it looks like 20 is the maximum (21 causes the device to stop functioning) ...
Hi All,
I am an electronics engineer but new to nRF51822 programming. I have used the PCA10000 & PCA10001 using Nordic SDK, using nRF Studio etc. In nRF Studio, you can...
