Tx Done Callback Problems

[bonedaddy]

I'm attempting to use the onTxDone callback function, but get the following error:

Board: Arduino Mega LoRa Shield: Dragino 915Mhz LoRa GPS Shield

/tmp/arduino_modified_sketch_308599/StandardFirmata.ino: In function 'void setup()':
StandardFirmata:28:10: error: 'class LoRaClass' has no member named 'onTxDone'
     LoRa.onTxDone(onTxDone);

Here's my sketch:

#include <LoRa.h>
/* LibP2P LoRa Transport Arduino Bridge

 * Data coming in through the serial interface leaves through the LoRa radio
 * Data coming in through the LoRa radio exits the serial interface
 * This is the "fast" version and operates on bytes instead of strings

This has yet to be pushed out in a release, so unless you're using the current master branch it would not be available.

[bonedaddy]

How unstable is master at the moment? I'm not doing anything mission critical atm and just experimenting with the platform so possible bugs and stuff aren't the biggest issue.

@morganrallen: When will the txDone and cadDone be available in the new release. Let say v0.8.

Are we pending for more testing? Thanks a lot.
