We are developing a product based on the CYBT-343026-01. We've programmed it with the EZ-Serial firmware version 1.2.29  and are  testing communication with a host MCU via serial.

The engineer doing the testing reports that when the EZ-Serial firmware is sent the command to enable hardware flow control that the RTS line is activated only when there is a BT/BLE connection. This is the case even when the CYBT is in command mode. This has the effect of stopping command communication with the host MCU.

We can't find release notes for version 1.2.29 of the firmware. The most recent notes cover release 1.2.27 which states that UART CTS is not implemented.

We have a few questions about the EZ-Serial firmware
1. Is there an update in progress that will address hardware handshaking?
2. Are there release notes available for version 1.2.29?
3. Is EZ-Serial for CYBT-343026-01 available in source form so we could make necessary fixes?

Thank you

Hi,

Could you please share what commands are you using and what was the response? if there is any log, it will be helpful for us to understand the situation.

Please find the release note of 1.2.29 on the below page.

Thank you - I've asked the engineer to detail the sequence of events.

The engineer did resolve the RTS problem. There was a conflicting signal on that IO line.

So I think the one open question for our application - is there an update planned to implement CTS handling? The release note for version 1.1.14 state that CTS is not implemented.
