3 Hardware Setup
This section details the hardware requirements for running the various BM70/71 ASF demo applications.
The following are the instructions for the hardware setup to work as a GAP-Central and
GAP-Peripheral device according to the application requirement.
- Plug the BM70/71-Xpro into the
EXT1 header of SAML21 Xplained Pro as illustrated in the following figure.Note: Step 1 is common for both the GAP-Central and GAP-Peripheral device.
- For the GAP-Peripheral device,
plug in the BNO055 board into the EXT2 of SAML21 Xplained Pro as illustrated in
the following figure.
