LAUNCHXL-CC1310: What is the max packet length (MTU) which TI 15.4 stack can support ?

What is the max user application payload length when security is enabled or disabled ?

According to this thread :

https://e2e.ti.com/support/wireless_connectivity/proprietary_sub_1_ghz_simpliciti/f/156/t/562570?tisearch=e2e-quicksearch&keymatch=TI%2015.4%20max%20data%20length

The maximum packet length TI 15.4-Stack can support is 500 Bytes.

It seems that user's application has to do the packet fragment manually before sending data to TI 15.4 stack ?

    Hey Kevin,

    The MTU packet length is 2047 bytes. This is not recommended since it can lead to network instability from occupying the air for too long, and if data corruption occurs the retries will be detrimental to battery life. This is why we recommend fragmenting packets. Yes the example applications do not handle data fragmentation, this will need to be implemented for your application.
