nRF8001 Bluefruit LE Breakout

Post by bartloos »

I have a little question about this board.
Does this work similar to jy-mcu modules? I just want to sent and receive some bytes from my iPhone to a logging device.
Does it have a logic level shifter in it? Now I'am using the jy-mcu H06 and i can receive bytes on 5v but sending it on 3,3v I have to shift it up to 5v.

Thanks!

I'm not familiar with the jy-mcu device, but our nRF8001 does have an HEF4050 level shifter built into the board. It will work with 3.3v or 5v microcontrollers.

Thanks for the reply!
I ordered a module and received it yesterday. But i can't find it when searching for bluetooth devices with my iPhone 5s.

For now i used hooked up 5v to VIN and GRND through Arduino. Only by powering it should it show up on my iPhone?

Probably not. The nRF8001 use an SPI-like protocol and needs to be initialized.

This tutorial shows how to make the hardware connections it needs: https://learn.adafruit.com/getting-star ... rything-up
