Hello, how are you? . The device communicates, it goes to sleep but never gets up again, can you help me with this? .
Frecuency : AU915MHZ
I leave you the code that I am using.
I’m using the following code:
/* The example is for CubeCell_GPS,
- GPS works only before lorawan uplink, the board current is about 45uA when in lowpower mode.
*/
#include “LoRaWan_APP.h”
#include “Arduino.h”
#include “GPS_Air530.h”
#include “GPS_Air530Z.h”
#include “HT_SSD1306Wire.h”
Air530ZClass GPS;
extern SSD1306Wire display;
//when gps d, if in GPS_UPDATE_TIMEOUT, gps not fixed then into low power mode
#define GPS_UPDATE_TIMEOUT 17000
//once fixed, GPS_CONTINUE_TIME later into low power mode
#define GPS_CONTINUE_TIME 15000
/*
set LoraWan_RGB to Active,the RGB active in loraWan
RGB red means sending;
RGB purple means joined done;
RGB blue means RxWindow1;
RGB yellow means RxWindow2;
RGB green means received done;

Number of trials to transmit the frame, if the LoRaMAC layer did not
receive an acknowledgment. The MAC performs a datarate adaptation,
according to the LoRaWAN Specification V1.0.2, chapter 18.4, according
to the following table:
| Transmission nb | Data Rate |
|---|---|
| 1 (first) | DR |
| 2 | DR |
| 3 | max(DR-1,0) |
| 4 | max(DR-1,0) |
| 5 | max(DR-2,0) |
| 6 | max(DR-2,0) |
| 7 | max(DR-3,0) |
| 8 | max(DR-3,0) |
Note, that if NbTrials is set to 1 or 2, the MAC will not decrease
the datarate, in case the LoRaMAC layer did not receive an acknowledgment
