File Transfer from Mobile to RaspberryPi device and Laptop Over WIFI and Bluetooth

Application type: Android App Technologies: Android , Java, Backend Service: Java based Rest API Code Based: We have mature base code with File Browser code QR code scanner, Bluetooth , Wifi code and Proper defined Activity and Fragment flow. Code is very clean, readable and easy to maintainable. Project Description: Android app that will transfer the pdf/doc/ppt file to raspberryPi , laptop over the wifi without human intervention. For Wifi connectivity, wifi credential /password,SSID etc details are read from QR code. So the flow will be Step 1: Select file Step 2: Call Cost Services Will Provide dummy Cloud API for cost [actual cost read from encrypted Doc but not bother about this functionality] Step 3: Integrate with Paytm [mandatory], GPay [As of now Optional] On Successful Payment initiate File transfer initiate as per below statement. Step 4: Scan QR code and get WIFI connectivity details Step 5: Connect to Wifi and Send file to WIFi enabled Device [RespberryPi, Laptop ] Step 6: on Receive file at device and Take Action basic action let say copy in other directory or add entry in SQLLite at receiver device. File Receive without human intervention. Note: We want receiver program as client that running on Raspberry Device as part of the solution. Acceptance Criteria: During / After deal will explain. Based on completion of this task have more task on same Android APP. This task is deal maker for Android project and will pay bonus amount also. Budget is constraint for me but I do'nt want to compromise on this functionality. If it is perfectly working I will pay 10+% as bonus of top of deal. Its Business deal as well for future tasks.
