In our existing products (using CYBLE-022001 module on a custom MCU board), we use CYSPP mode to establish a 'pipe' to our other software running on a PC. Our MCU firmware is required to use 9600 baud rate, or must add arbitrary wait states after sending 10 bytes or so, to guarantee that the data has been transferred over the air before sending the next packet.
I'm looking for methods of getting faster/more robust communication, such as ACK/NAK returns at the BLE level on successful transmission of a given data-packet. This may not be possible given that CYSPP mode is a pipe and bypasses BLE module commands.
I assume binary vs ASCII command-modes don't provide any better MCU knowledge of connection throughput.
It is difficult to tell where the issue lies, since once in CYSPP mode, the radio-link is a black-box.
