HTCC-AB01 Can't work in AS923 band

Dear All,

I have use HTC-AB01 to config it for AS923 band and use the LoRaWan_interrupt.ino program to check it. The device will hang-up after “join failed” around 40 second. But I try to config it to band AU915, it is working normal, it will try to re-join the network after 30 second. Pls comment on this problem and help me to fix it.
