It’s likely that the join is arriving in the second transmission slot so you’ll need a

  LMIC_setDrTxpow(DR_SF7, 14); // Set data rate and transmit power for uplink (note: txpow seems to be ignored by the library)

  TRACE_SX("TMP_Mode", eeData.TMP_Mode)

to set that up so it knows what to listen for.
