Use of NR51822 with arduino

[davisse]

hi i'm using the nrf15822 beacon for an application of communication on arduino I just would like to understand how i should start to stream my data using the beacon beacause i'm new to using bluetooth modules and comms

is the communication made via a serial port ? do u ahve any docs on how to use it with an arduino or a pi ? thx a lot davisse

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.

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

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?

what "PCB" are you looking at?
