ESP32 reboots continuously (RTCWDT_RTC_RESET)

[mpy_ok_10]

I have a problem with the reboots of the ESP32. I am new at this Forum and I hope you can help.
My Program runs in an endless-loop where the ESP32 sleeps for some ms and is awake for some ms.
When the ESP32 is awake scans the bluetooth.
But the ESP32 reboots all the time. After hours and also after a few minutes.

Here is my main.py:

Code: Select all

def ble_irq(event, data):
    #print(event)
    #print(data)
    if event == const(5): # scan result
        if data[4] == bytearray(b'TEST01'):
            ble.gap_scan(None)
            #make some stuff
            ble.gap_scan(0, 100000, 100000)

ble = bt.BLE()
ble.irq(ble_irq)
ble.active(True)
ble.gap_scan(0, 100000, 100000)

while True:
    time.sleep_ms(300)#BLE scannen
    machine.lightsleep(200)#machine sleep
