BLE for me is a new thing thank you Code: dim hb(9)as byte hb(0)=0 hb(1)=-43 hb(2)=10 'orginal 5 hb(3)=20 hb(4)=35 hb(5)=80 hb(6)=0 hb(7)=0 hb(8)=0 hb(9)=0 manager.writeData("00001554-1212-efde-1523-785feabcd123","0000155f-1212-efde-1523-785feabcd123",hb)

E emexes Expert Licensed User Longtime User Apr 26, 2019 #2 Can you write and read back the change using nRF Connect? Many interfaces uses separate characteristics for writing and reading what looks like the same piece of information, eg: "In response to each write on UUID 00001524…, the device quickly sends a notification on a different bluetooth characteristic UUID = 00001525-1212-efde-1523-785feabcd123" from (randomly chosen example) https://community.home-assistant.io/t/radoneye-ble-interface/94962 Upvote 0
