1. 能否提供能够正常使用的Direct TX RX Demo?
The 32bit MCU SDK has offered some examples which include direct rx an direct tx demo code for EZR32 parts.
You could create these examples based on one of the silabs' standard kits with EZR32HG part.
Below is a simple/common guide for how to create simple example code for EZR32.
SimplicityStudio -> Launcher -> Solutions -> type EZR32HG -> then select one proper kit -> pitch on the kit name -> New Project -> select the latest 32bit MCU SDK -> Example -> select one of the demo -> finish to create.
2. 如果设置了MODEM_OOK_CNT1 低2Bit为1，即开启SQUELCH 功能后，则一直无法进入接收数据状态 .
MODEM_OOK_CNT1 is only used for OOK, please don't modify it if you use other modulation type. If not, some other uncontrollable problems may appear.
