# INAV VTX+ & Bluetooth Setup

Holybro Kakute H7 V2 PINIO Setup for INAV 5.1 This manual applies to INAV 5.1, Holybro Kakute H7 V2 and covers the topic of PINIO functionality setup so that following goals are achieved:

2. Built in Bluetooth is disabled when INAV is armed
3. VTX is always enabled or activated on a switch 

### Arming and Bluetooth setup 

In this scenario, arming is assigned to Channel 5. USER1 mode, which drives the Bluetooth module is assigned to the same channel. When INAV is armed, USER1 is enabled as well and disables Bluetooth
