When no water is consumed, my module sends a LoRa message every hour including battery voltage...
As you can see on the log below, the first message occurs one hour after the module has started.
Ok, everything fine here ... EV_TXCOMPLETE occurs 2sec after paket queued which seems to be ok.
But...starting from the second message....you can see that the EV_TXCOMPLETE event occurs 12min45s after packet has been queued ...
Even worst on the third message...EV_TXCOMPLETE event occurs after 23min from paket queued ...
Then on the 4th...everything's fine again....
Can someone have an explanation ? and a workaround ?
I forgot to mention that I did not see any problems when I am consuming water ... because (I thing) messages are sent very often...The problem seems to occur when no message has been sent for a long time (here one hour).

Recall : When no water is consumed the sensor is sending a message everyhour (with the bug described on this issue)...I reduced this interval to 30 minutes....and everything works like a charm.
You can write to the reg and change the opmode. The TX does not happen because there buffer is still busy or not entirely freed after the last TX event. buggy code i guess.
You can debug the LMIC.opmode and check if its not at OP_TXRXPEND.
Serial.println(F("OP_TXRXPEND, not sending"));
this is how i got rid of it
os_radio(OP_TXDATA);
LMIC.opmode = OP_TXDATA;
LMIC_setTxData2(1, mydata, sizeof(mydata)-1, 0);
Hi,

2 things I have already tried :
LMIC.bands[BAND_MILLI].avail = os_getTime();
LMIC.bands[BAND_CENTI].avail = os_getTime();
LMIC.bands[BAND_DECI].avail = os_getTime();
LMIC_setClockError(MAX_CLOCK_ERROR * 10 / 100);
