Default LoRa sync word value

What is the default public network mode in LoRa ping pong example? There is a function of RadioSetPublicNetwork which can be configured, but if we do not configure it at all, what will be the default mode? Public or Private?

Also, how can I set my own private syncword? I thought it doing like this, but compiler is generating implicit declaration error in SUBGRF_WriteRegister() function

Hello @pho3nix 

the default network mode in LoRa ping pong example is the LoRa private network.

Best Regards.

The Ping-Pong example doesn't use a public network - it's just two devices send messages to each other.

    Exactly but the default setting of the SYNCWORD is LoRa private network as indicated on the RM0453.

    Best Regards.

      Thanks for your response, but how can I set my own sync word, default is 0x1424, but let's say I want to set 0x1122, how can I do that? Should I include radio_driver.h file and call SUBGRF_WriteRegister() directly, or there is any other better alternative out there?
