I want to send data from nrf51822 through UART TX to esp8266.

Hello, 

I am trying to send data from nrf51822 through UART TX to esp8266. I've gone through the app_uart examples and I can recieve data through RX but having difficulty sending data through TX.

What "difficulty", exactly?

What hardware are you using?

Can you successfully communicate (Tx & Rx) with a PC terminal? You should get this working before adding complications like an  esp8266!

Thanks for your reply. I've tried with a pc terminal.

I've even tested the sending data to the esp8266 from a different device and it works. But when i try with the nrf51822, I do not receive any data at all.

Please see my code above
