Hi,

What is the most efficient way to program these modules for mass with specific uart parameters? We want to reduce the steps in mass production. If the modules are shipped with 115200, the hos t MCU won't be able to communicate with the module as the host lacks the run time change for baudrate.

Thanks,

Se

The EZ-Serial FW source code is not avaliable for customers. If you need a customized EZ-Serial FW, please contact your local FAE/Marketing for help.

Do you develop the FW by yourself or use the EZ-Serial FW?

If you develop the FW by yourself, you can program the device with the module programmer: WICED Module Programmer User Guide – KBA225060

If you are using the EZ-Serial FW and needs to change the PUART baudrate, you may need to use the "STU" command to change the default baudrate before you put the module on your board.

I am using EZ-serial. Thank you for your response.

Do developers have access to the Ez serial firmware files to change the default baudrate and maybe upload the firmware using the OTA option?

Where can I find the list of local FAE/Marketing for Cypress?

You can also change the uart baudrate by yourself with a USB-UART tool with the "STU,   " command. I think the workload will be no more than re-program the module.

We will be outsourcing the assembly process and are concerned we may lose the communication if the module accidentally gets factory reset. Thus if it has the required baudrate as factory configuration, the assembly process is easier and fail safe during the usage.

Where do you get the module? You can contact the distributor who provides you the product.

We bought the development board on digikey and currently made the connections with the host MCU using the headers.

What is the maximum throughput achievable using this module in ez-serial mode with 921600 baud rate?
