lorawan module: White Screen after lora.setDeviceMode(LWOTAA)
-
I try to use the lorawan module. The device starts but crashes (and start again) when trying to set device mode to OTAA.
Can anybody help?
Here's the code
--- cut ---
#include <M5Stack.h>
#include "LoRaWan.h"//LoRa
char buffer[256];
long sentMillis = 0;
long currentMillis = 0;
long interval = 15000;
//byte payload[2];void setup() {
/* Prepare M5STACK */
M5.begin();initlora();
M5.Lcd.println("Started");
}void loop() {
currentMillis = millis();
if (currentMillis - sentMillis > interval) {
sendobject();
}M5.update();
}void initlora() {
lora.init();
delay(1000);
memset(buffer, 0, 256);
lora.getVersion(buffer, 256, 1);
Serial.print(buffer);memset(buffer, 0, 256);
lora.getId(buffer, 256, 1);
Serial.print(buffer);lora.setId(NULL, "aaa", "bbb");
lora.setKey(NULL, NULL, "ccc");M5.Lcd.println("setDeviceMode");
lora.setDeviceMode(LWOTAA);
M5.Lcd.println("setDataRate");
lora.setDataRate(DR5, EU868);lora.setChannel(0, 868.1);
lora.setChannel(1, 868.3);
lora.setChannel(2, 868.5);
lora.setChannel(3, 867.1);
lora.setChannel(4, 867.3);
lora.setChannel(5, 867.5);
lora.setChannel(6, 867.7);
lora.setChannel(7, 867.9);lora.setReceiveWindowFirst(0, 868.1);
lora.setReceiveWindowSecond(869.525, DR3);lora.setPower(14);
lora.setPort(1);
lora.setAdaptiveDataRate(true);
//lora.setDutyCycle(false);
//lora.setJoinDutyCycle(false);
while (!lora.setOTAAJoin(JOIN, 10));
}void sendobject() {
bool result = false;sentMillis = millis();
M5.Lcd.println("Sending");
result = lora.transferPacket("Hello World!", 5);
//result = lora.transferPacket(payload, sizeof(payload), 5);if (result == true) {
M5.Lcd.println("Sent");} else {
M5.Lcd.println("Error");
}
}
