LT-22222-L: State of RO1, RO2, DO1 and DO2 loss after reboot or power off

Hi, I use LT-22222-L with firmware AS923 v1.5.7. I set the state of RO1, RO2, DO1 and DO2 to ON and all LED indicators are ON. I find the state of RO1, RO2, DO1 and DO2 loss after reboot (by ATZ) or power off (by unplug the power). The state of RO1, RO2, DO1 and DO2 is back to OFF instead of keeping ON.

This issue should be already fixed in v1.4.2? https://www.dragino.com/downloads/downloads/LT_LoRa_IO_Controller/LT22222-L/image/changelog Image v1.4.2

Update LoRaWAN stack to DR-LWS-003 (http://www.dragino.com/downloads/index.php?dir=LoRa_End_Node/DR-LWS/&file=changelog )
Fix DO / Relay state lose after reboot. Now After reboot, the DO/Relay will keep the same state as before.

Please help to check v1.5.7 if the issue happened again or there is any temporary workaround. Thanks a lot.
