Hi project owner. I'm a senior software developer. I have over 7 years experience in mobile development and over 10 years in embedded system design. I've done similar project to send data via bluetooth from microcontroller. I believe I can make similar to you. I will make the mobile app using cordova and the microcontroller will be arduino, or it might be possible with BLE module it self without need any additional MCU. Please consider my bid and I hope you want to talk more detail about this project over chat. Regards, Teguh
