Unable to send packet

[Roberto6969]

Is there any way to debug sending process? I have problem with two almost identical sensors and SW. In loop is: void loop() { do_send(&sendjob); os_runloop(); }

at the end of do_send(osjob_t j) is LMIC_setTxData2(1, message.getBytes(), message.getLength(), 0);
Serial.println(F("Packet queued"));

So the problem is the sending process stops with the message: Ready to send message of 1533 bytes size and 8 bytes length. Packet queued

How can i find out where the sending process hangs?

Thank you!

Did you try the LMIC_PRINTF_TO and LMIC_LOGLEVEL macros (they might be called slightly differently) in config.h?

Also, if you're trying to send a 1533 byte message, that's your problem - LMIC has a max message size of 50 bytes or something (64 bytes minus headers) IIRC.

Actually i don't send so much data. Here is th code which shows 1363 bytes of data but it is not true - as you can see i sending only ".addUint16(p);" and this could not be so long: // Prepare upstream data transmission at the next possible time.

LoraMessage message; // clear 
readVoltage();
readMeteo(); // reading data from BMP280
message
//.addLatLng(-33.905052, 151.26641)
//.addUnixtime(1467632413)
//.addUint8(10)
//.addUint16(v) * * * * *
//.addTemperature(t)
//.addHumidity(h)
.addUint16(p);
/* to vklopiš za test 2 */
Serial.print(F("\nReady to send message of "));
message.getBytes();
Serial.print(F(" bytes size and ")); Serial.print(message.getLength()); Serial.println(F(" bytes length."));

And about debugging: whenever i uncomment lines //#define LMIC_DEBUG_LEVEL 2 and //#define LMIC_PRINTF_TO Serial i receive error at compiling. Is there something i missed?

You'll have to tell us the error you got, we're not psychic :-) If you're running on a non-AVR board, the commits from the non-avr-printf branch might be helpful (IIRC I wrote them, but haven't gotten suficient testing results yet for merging that branch).

Well, you are doing great job so you could be a magician ;-)

Here is the error at the time of compiling:

So this error happens only when i uncomment those two lines. I am running this on Atmel ATMEGA328P (only chip with minimum components). This configuration has worked for some time - rouhgly before two months.

I just fixed the compilation problem with LMIC_DEBUG_LEVEL > 1 in git master.
