Develop firmware for nRF52 DK with FreeRTOS using Bluetooth

We need a basic foundation for a Bluetooth communication between a PC and a probable device with a nRF52832 chip. We use nRF52 DK from Nordic Semiconductors to start with.

Flowing need to be established on nRF52 (PCA10040):

• RFCOMM protocol because it has save packet deliver.
  
• FreeRTOS need to be setup to run with BT stack.
  
• I2S DMA for both send and receive.
  
• SPI DMA for both send and receive.
  
• GCC Tool chain (c/c++) must be used.
  
• nRF5 SDK v16.0.0 must be used.
  
• Able to swap between Bluetooth standards 4.0, 4.1, 4.2 and 5.0

Following need to made for PC app and accessible from GUI:

• Able to select probable device (nRF52 DK) for connecting.
  
• Adjustable transmitting rate from PC to nRF52 DK going from 1 to 10 Kbit (random data)
  
• Adjustable transmitting rate from nRF52 DK to PC going from 5 to 100 Kbit (random data)
  
• Live charts showing RX and TX transmitting quality (Packets there need to be resend)
  
• Able to save transmitting quality from charts to a CSV file.
  
• Able to select used BLE protocol between 4.0, 4.1, 4.2 and 5.0

We have no skills in Bluetooth programming but have 30-years in MPU programming and 5-years in PC c# programming.

We need a detailed step by step instruction on how to setup the received material to establish the first connection and test.

We expect to revived the flowing thing:

• Detailed step by step instruction on how to setup the received material to establish the first connection and test.
  
• Compiled .exe file of the PC app
  
• Compiled .HEX file of the firmware for nRF52 DK
  
• All source codes for PC app
  
• All source codes for firmware.
