How are the four RAM banks divided up in the nRF51822? Is it an even split of the 16K total RAM (i.e. 4K per block)?
Furthermore, can I expect strange results if I turn...
Hello, sirs.
My question is how to configure clock in gazell protocol on nRF51822
I look at the example gzp_dynamic_pairing but that does not have a code part of modifying...
I want to stream data continuously from a sensor to a host, using BLE.
Using the nRF8001, I have defined a GATT server, with notification.
From an Android phone, I open...
Can the nRF51822 handle more than one connection at a time? I suspect that the answer 'no' based on some indicators, but it'd be good for me to get a conclusive answer. Thanks...
