i didnt see any RX or TX pin on pcb

what "PCB" are you looking at?

Ok i assumme you wanted to use beacon as serial bluetooth (like in other bluetooth devices, by AT commands or something). It is not possible directly.

If you want something like this:

arduino/rpi <----UART----> nrf51 <---- BLE -----> mobile phone or something with ble?

you can use nrf51 with serialization (you can find example in SDK) and use ble calls directly from arduino/rpi, or just use nrf51 as independent bluetooth host and only communicate by some kind of commands with rpi/arduino. You can use nordic uart service with that so you have something like uart via ble.

Consider that nrf51 is more powerful than arduino and maybe you dont need arduino - just do everything on nrf51?

ok maybe i misunderstood the use of the beacon dunno what i want is to send data from and arduino or an RPI ( commands for DC motors and servos) is the beacon capable of that, i didnt see any RX or TX pin on pcb so i'm quite in the dark

nrf51822 is normal microcontroller (much more powerful than AVRs on arduino...) so it acts exactly as it is programmed. you could describe your use-case in more details so maybe you will get some clues.
