Hi team,

A customer has needs to send a large amount of data over TI 15.4-stack. Is it possible to increase the payload size of MAC layer to more that 256 bytes for CC1312R? Thanks.

Hi Shuyang,

It is not recommended that users increase the MAC_MAX_FRAME_SIZE beyond the preset values. They will need to fragment their packets and send them as an array of data. It is possible to use the OAD examples as a reference. Here are some relevant E2E threads to help with their application:
