E emexes Expert Licensed User Longtime User Sep 17, 2019 #3 My apologies: need to do a SetIndication, rather than SetNotify. The characteristic is: 0000ffe1-0000-1000-8000-00805f9b34fb sometimes referred to in shorthand as just ffe1. This post seems to confirm success: https://www.b4x.com/android/forum/threads/bluetooth-4-0-data-exchange.103107/page-3#post-647113 and this blog post about the HM-10 BLE UART module is worth a read: HM-10 Bluetooth 4 BLE Modules - Martyn Currey Upvote 0
