LMIC_ASSERT(readReg(RegOpMode) == 0x10); fails in txfsk (after waking up from cpu.sleep(10)) #388

Open elsbiet opened 3 years ago

.. lora.attach(lora.BAND868)

lora.setAppEui("***.. ") lora.setAppKey("**..")

lora.setDr(7) lora.setAdr(true) lora.setReTx(4) lora.join(lora.OTAA) lora.tx(false, 4, pack.pack(msg)) ..

will crash the system (at least on my esp32) soon after waking up from cpu.sleep(10). if i move lora.setDr(7) 1 line down the system will run fine.

the crash is the consequence of a failed assertion in static void txfsk () - RegOpMode contains 0. i feel this might be the consequence of the (partly uninitialized) global variable LMIC - i have never requested fsk-modem operation.

is there anything to do before sending the cpu to sleep?

I guess you mean this assert in file components/lora/node/lmic/radio.c on line 436 LMIC_ASSERT(readReg(RegOpMode) == 0x10); That would be a little strange though, as the line before set's the RegOpMode register to exactly that value: writeReg(RegOpMode, 0x10); // FSK, BT=0.5

Please confirm. If so, you could probably try to put a while instead of the LMIC_ASSERT and just re-execute the line that is setting the RegOpMode. Like e.g.

    while(readReg(RegOpMode) != 0x10) {
        // select FSK modem (from sleep mode)
        writeReg(RegOpMode, 0x10); // FSK, BT=0.5
    }
    // enter standby mode (required for FIFO loading)
    opmode(OPMODE_STANDBY);

That could make sure that even when coming out of wakeup, the register should properly be set.
