+# 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.
