how can i do a new characteristic ( all new 128bit-uuid )Under the same service
this is i try use nrf connect to do this , i hop add new different from NUS servic ( only change 16bit uuid ) , how can i do?
have any example ?
thankes ~
sdk15.3 / nrf52810 / s112_v6.1.1
thank you , i find this link
try to do this
Can you help me check this?
have any wrong?
