# Wireless connections
From INAV 5 onwards, the Configurator supports wireless connections via Bluetooth Low Energy (BLE) and Wifi (UDP and TCP).
## BLE
The following adapters are supported:
- CC2541 based modules (HM1X, HC08/09)
- Nordic Semiconductor NRF5340 (Adafruit BLE Shield)
- SpeedyBee adapter
Flightcontrollers with BLE should also work, if you have an adapter/FC that doesn't work, open an issue here on Github and we will add it.
### Configuring the BLE modules
Activate MSP in INAV on a free UART port and set the Bluetooth module to the appropriate baud rate.
Example for a HM-10 module:
Connect the module to a USB/UART adapter (remember: RX to TX, TX to RX), and connect it to a serial terminal (e.g. from the Arduino IDE),
Standard baud rate is 115200 baud, CR+LF
```
AT+BAUD4
AT+NAMEINAV
```
The baud rate values:
| Value | Baud |
|------|------|
| 1 | 9600 |
| 2 | 19200 |
| 3 | 38400 |
| 4 | 115200 |
There are many counterfeits of the HC08/09 modules on the market, which work unreliably at high baud rates.
However, it is recommended to avoid these modules and to use an original HM-10.
### SpeedyBee adapter
Just connect it to the USB port, no further configuration needed.
## TCP and UDP
Allows connections via Wifi.
Hardware:
- DIY, ESP8266 based:
This project can be used to make INAV Wifi enabled: https://github.com/Scavanger/MSPWifiBridge
A small ESP01S module should still fit anywhere.
- ExpressLRS Wifi:
Should work (via TCP, port 5761), but untested due to lack of hardware from the developer. CLI and presets do not work here, problem in ELRS, not in INAV.
