We have our custom NRF52840 board but never used BLE communication. We have an application where we need to send data to SCADA wirelessly. We have programmed our UART to receive command from SCADA through RS485 modbus protocol and now wirelessly we need to extract data from a similar board which is around 100m distance. That board is connected to multiple devices through RS485 port. Can you guide how to initiate BLE in our board and send and receive data between two BLE boards. Can somebody explain step by step process.
