¿Support ESP8266?

[sabas1080]

Hi

Could this work with esp8266?

Thanks

[johanstokking]

The ESP8266 runs Arduino and it can probably set up a serial connection with a Microchip RN module, so I guess it does.

[sabas1080]

The Version 2.1.0 does not work I can use version 2.0.0 with some modifications work But it seems to be the serial does not work

[johanstokking]

Do you have an error message, or can you elaborate on "does not work" ?

I have the next error via serial

Thanks

I think this is related to #172. We're doing some dirty pointer stuff in readLine(). Will fix it

[sabas1080]

okey, thanks I'll keep up

Hi @johanstokking

I have tried with the latest version of the library and it seems I still have the same error or simply does not print anything

I'm trying with this sketch (Software Serial ESPsoftwareserial) and similar error:

I

#include <TheThingsNetwork.h>
#include <SoftwareSerial.h>
#include <Wire.h>

// Set your AppEUI and AppKey
const char *appEui = "AAA6789AA2311986";
const char *appKey = "000000006723FFEEBB11116734230000";

SoftwareSerial loraSerial(12, 14); // RX, TX !! labels on relay board is swapped !!

//#define loraSerial Serial1
#define debugSerial Serial

// Replace REPLACE_ME with TTN_FP_EU868 or TTN_FP_US915
#define freqPlan TTN_FP_US915

TheThingsNetwork ttn(loraSerial, debugSerial, freqPlan);

void setup()
{
  loraSerial.begin(57600);
  debugSerial.begin(9600);

  // Wait a maximum of 10s for Serial Monitor
  //while (!debugSerial && millis() < 10000)
  //  ;

  debugSerial.println("-- STATUS");
  ttn.showStatus();

  debugSerial.println("-- JOIN");
  ttn.join(appEui, appKey);
}

void loop()
{
  debugSerial.println("-- LOOP");

  // Prepare payload of 1 byte to indicate LED status
  byte payload[1];
  payload[0] = (digitalRead(LED_BUILTIN) == HIGH) ? 1 : 0;

  // Send it off
  ttn.sendBytes(payload, sizeof(payload));

  delay(10000);
}

Thanks

What about the serial passthrough, see also an example of the library?

If it has to do with memory allocation of this library, then the serial passthrough should work. If it has to do with serial interfacing in general, that will crash as well.
