How to update BT+BLE Bridge firmware

update BLE bridge firmware cover

BLE Bridge module acts like a bridge/tunnel sending any incoming data from your GNSS receiver towards the listening device and sending all incoming data from your BLE device to your GNSS receiver.
It does not contain any other logic and is ideal for iOS developers and developers of any platform where classic BlueTooth (BT2.0) is not supported.

In this tutorial, we will guide you through the process of updating the BT+BLE Bridge firmware or converting your WiFi NTRIP Master into a BT+BLE Bridge (and vice versa). Note that the WiFi NTRIP Master and BT+BLE Bridge share the same hardware, and the conversion is achieved by updating distinct firmware.
