RS485 communication for nRF51822

[Gomathi]

I want to make rs485 communication with nRF51822. I gone through the UART code, there CTS , RTS pin are required , but for my case tx, rx,rx enable is enough, and also shall i use the UART code over here (rs485). its possible or not????

i tried also but not getting any output in hyper terminal.

let me know how to enable the communication

Your best bet is to place a UART to RS485 converter between the nRF and your PC.

An example of one of those board is here: www.sparkfun.com/.../10124

This is by no means the only one out there, just the first one that came up in a Google search.

Setting up app_uart with APP_UART_FLOW_CONTROL_DISABLED will require you to define the CTS and RTS pins, but it never actually sets them up.
