If I remember correctly, it’s about 90 bytes in a single packet.

same question for UART....
Maximum number of bytes that I can transmit over UART??

For UART, it depends on UART buffer, I remember the default buffer is set to 128 in Z-Stack 3.0.1 and this limits the max bytes you can send over UART.

Jay,

The maximum application data length for over-the-air packets is 116 bytes as defined by MAC_MAX_FRAME_SIZE in mac_api.h.

YK,

The default for UART is actually 256 but we recommend reducing to 128 for CC2530 RAM optimization: processors.wiki.ti.com/.../Optimizing_Flash_and_RAM_Usage_of_Z-Stack_for_CC2530
