In our earlier projects with nRF51 and SDK 8 we used to have bluetooth device names of length 13 or 14 characters. However, when using nRF52 and SDK 12 I noticed that the...
This is what I believe, of course, my beliefs are flawed, so please DO point my errors out:
There is this attribute table on server/peripheral devices. The actual...
Hi，Nordic
