What is the limit of data transmission? Which one is the maximum payload size?
It is a little bit confusing that, in the CySmart_Dongle example for BLE KIT, inside CySmt_TransportLayer.h,
/* Both UART RX & TX buffers are set to maximum 5K with assumption that L2CAP MTU will be with-in this limit */
However, UART_UART_TX_BUFFER_SIZE is defined as 550u, and not hexadecimal, which is different with 5K.
So, how big on earth is the maximum of the MAX_PAYLOAD_SIZE?
