BLE communication of 1st party hardware component of Android APP

BLE communication of 1st part hardware component of Android APP We are looking for a developer that can build the BLE (Bluetooth) component of our app. We have a hardware device (1st party) that requires communication of BLE within our app. The requirements (not limited to) follow: - Syncing Data from Hardware Device and sending it to database while app is in foreground - Syncing Data from Hardware Device and sending it to database while app is in background - Syncing Data from Hardware Device and sending it to database while app is in background when in a certain proximity (location) - Configuring device (sending a few flags to Hardware Device) - Update Hardware Device DFU (firmware). This requires getting DFU from our server and sending it to the Hardware Device. - Supporting multiple Firmware versions for syncing data, configuring device or uploading DFU - Deleting Hardware Device from our server and sending configuration to Hardware Device afterwards - support connecting to multiple devices - Observable RSSI for other parts of app - Access to Hardware Device Serial number to other parts of app - Access to connected devices to other parts of app We'd send you a test unit of our device to complete these tasks. but this does limit our development to only developers in the USA. Hourly: $25 USD / Hour Milestones Milestone 1 - BLE initial communication with device - Creating a device profile - Serial Number - Fill serial number - Battery level - Firmware version - data available flag / measurements available flag - Received last data flag - Is registered flag - BLE interface version - Establish a bluetooth session Milestone 2 - Configure a device - UI will be provided - Send configuration to DB - send a flag to device indicating the device is configured - Extendable function calls to check if device is configured in any part of app - Support connecting to multiple devices Milestone 3 - Syncing Data from Hardware Device and sending it to database while app is in foreground - Syncing Data from Hardware Device and sending it to database while app is in background - Syncing Data from Hardware Device and sending it to database while app is in background when in a certain proximity (location) Milestone 4 - Check device firmware version to servers latest firmware available - Update device firmware (DFU upload) - Download DFU from server - Send DFU to device Milestone 5 - Supporting multiple Firmware versions for syncing data, configuring device or uploading DFU - Observable RSSI for other parts of app - If RSSI changes, we’ll need to change certain parts of the according to RSSI number.
