BLE is a version of Bluetooth that has a lower energy consumption when compared to classic Bluetooth. Lower costs while maintaining the same communication range make BLE a viable wireless personal area network for many products including mobile operating systems iOS, Android, Blackberry and Windows 10. BLE is primarily used for video games, security, healthcare and fitness, PCs and mobile phones.Hire Bluetooth Low Energy Developers
You can use any open source react-native-ble-manager and react native mqtt. There will be 2 pages to the react native app. One page will be a simple UI for mqtt. It contains host, port, clean session, client id, subscribe topic, publish topic , connection , qos, keep alive. When the connection is successful, it should be possible to publish hex code and receive/display subscribe topic. Another page will be a simple UI to send ble data to ble device and to get ble device response. For mqtt, the connection must cater for TCP (SSL/TLS is false), one way SSL and 2 way SSL (TLS/SSL is true)with selection of ca file, client certificate file and client key file .
Create a project in STM32CubeIDE for STM32WB5MMGH6 to use bluetooth to connect to an APP. The project must meet this requirements: 1- SERVICE_UUID_1 to be inserted in a #define example : #define SERVICE_UUID_1 "fffffffffff-000000-1111-ffff-1111111111" 2- must have 6 CHARACTERISTIC_UUID example : #define CHARACTERISTIC_UUID_11 "a601bcbe-4dc1-11ea-b77f-2e728ce88125" /* time_warm_up */ #define CHARACTERISTIC_UUID_12 "ba846344-4dc1-11ea-b77f-2e728ce88125" /* STATE: 1,2,3*/ #define CHARACTERISTIC_UUID_13 "ffffffff-000000000-b77f-2e728ce88125" /* On/OFF */ #define CHARACTERISTIC_UUID_14 "ffffffff-000000000-b77f-2e728ce88125" /* on /off 1 2 */ #define CHARACTERISTIC_UUID_15 "ffffffff-000000000-b77f-2e728ce88125" /* s1 */ #defi...
Please only contact me if you can provide me a well written project written in flutter (dart) and allow me to look at it + have a previous proved experience with BLE IOT devices The app is in a very advanced stage and a lot of code was written already and a lot of plugins were used already. currently there is a need for tweaks and changes but it will need a very deep understanding of the app and written code. the stack is flutter (with bloc pattern) , server api (with dio) firebase messaging and some native android+ios code for Universal links.....
Firmware Writer for USB , BLE Module and Sensors Communication 1. Require BLE module power on via USB 2. Require firmware written for sensors to communicate with BLE module. 3. Require BLE module communicate with mobile app. We do not require any App developing. Experienced Only! If you do not have time to professionally provide updates it best that you not place any bid.
