Hi,
I've created an application using the S110 experimental ANCS demo. I successfully implemented ANCS and then began to structure my application around it. At some point...
Hi,
it happened that we have some hardware boards populated with older chips rev. QFAACA and some with newer rev. QFAAG0 but we need to share same software. As I read newer...
by set a char with BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS, means it can't be read and write, if so, why not remove the char?
any reason behind BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS...
Is there anyway to limit the number of channels a device is advertising on?

Hi,
We want a throughput between a BLE link 12KBytes/s.
In our application there is a peripheral (in Nordic starter kit), running S110 and we have configured connection...
I have two questions.
Is it possible to use the DAP[n]/DAB[n] registers without using Bluetooth 4.0?
If it is possible, then how? I searched all the sample...
I am starting with Nordic nRF51822 and I would like to know if do you have some samples for use with emIDE (I liked it because you don't have size limitation). And I had some...
