@bgunnarb you are find the problem, i think i have arduino pro mini 3.3V but it's 5V. Thx very much it's work better now

Sorry for my poor english im french.
They havent solution for use only the tx/rx pin on both raspberry pi and arduino?

Ok thx, but i think it's could be possible to use it TX/RX pin on arduino. It's transparent wireless communication.

Hi all. I have a question.
Can i use drf1278dm with it ?
Best regards

Yes ^^ . can you give me at snyp_thx at hotmail dot fr?

Have you link for older library? Are you french?

i tested with 3.3V and 5volt but same result
http://www.banggood.com/fr/GY-68-BMP180-Digital-Barometric-Pressure-Sensor-Board-Module-p-1059025.html?rmmds=myorder

I supply itwith the 3.3 V output off arduino

I bought it in banggood, but it work's before...
