What's the max size limit on android.net.wifi.aware.DiscoverySession.sendMessage?

Unknown size limit of API: android.net.wifi.aware.DiscoverySession.sendMessage causes System.err

Link to documentation: https://developer.android.com/reference/android/net/wifi/aware/DiscoverySession#sendMessage(android.net.wifi.aware.PeerHandle,%20int,%20byte[])

Sending 620bytes of data using the child class of DiscoverySession;
PublishDiscoverySession.sendMessage

Logcat:
2025-02-04 15:59:06.890 21620-21728 MainActivity net.mobilewebprint.nan D Attempting to send message of size: 620 bytes 2025-02-04 15:59:06.893 21620-21728 System.err net.mobilewebprint.nan W java.lang.IllegalArgumentException: Message length longer than supported by device characteristics

The API works for very small msg size of 10bytes.

What's the system limit on this API? How do I find out what is supported max size based on device characteristics?

Details
Wi-Fi Connectivity / Bluetooth, Android Version:15, Pixel 7 Pro

Tried smaller size. The API works for very small msg size of 10bytes.

Here is the exception value after failed call.
