LED status
LED functionality is available with firmware version 2.7.0 and newer.
Reach Module boot LED sequence
Reach Module LED is an RGB LED that cycles through a simple pattern:
Network state -> App state
During boot Reach Module will go through 3 steps:
- Network scan
- Time sync
- Emlid Flow launch
Network scan
During boot, Reach Module enters a network scan state in which it will try to connect to any known Wi-Fi networks it can find. This might result in connecting to a previously added network or creating its own hotspot.
| Network state | Demo |
|---|---|
| Scanning |  |
| Client Wi-Fi mode |  |
| Hotspot Wi-Fi mode |  |
Time sync
After network configuration is done, magenta blinks will be added to the LED. They are shown during time sync.
The app will not launch until the time sync is complete. Internet connection allows this to happen automatically, but in hotspot mode Reach Module requires a connected antenna with some satellite visibility.
Emlid Flow launch and operation
After the time sync is done, the magenta blinks stop and Emlid Flow is launched. Green solid light will take its place, showing app start. You can see several additional states:
| App state | Demo |
|---|---|
| Normal app operation |  |
| Point collection |  |
| App internal error |  |
LED Behavior
The table below demonstrates possible flash patterns describing various states of the receiver.
| Reach Module State | Time Sync | Network | App Status | Sequence Demo |
|---|---|---|---|---|
OFF |  | |||
Lack of power |  Blinks each 10-15 sec |  | ||
Network scan | Fast blinks |  | ||
Time sync in client Wi-Fi mode | Solid | Solid |  | |
