Other Parts Discussed in Thread: CC2564MODA
Tool/software:
Hi,
We’ve integrated the Ezurio Sona TI351 module into our device for BLE communication, using SDIO for WiFi and UART for BLE. Our software setup includes the Ezurio backport kernel driver, their sample device tree, and TI firmware on a Linux system.
By default, the device tree sets the UART baud rate to 115200, which works fine. However, we need to increase it to at least 2 Mbps. When we attempt to modify the baud rate in the device tree, the module fails to connect. We also tried using btattach and manually sending HCI commands after establishing a connection at 115200, but the baud rate doesn’t change.
in my previous experience with another TI module (CC2564MODA), the BTS firmware file automatically increased the baud rate upon connection. However, this behavior isn’t present in the CC3351 BTS files.
• Are there BTS files available for the TI351 that support automatic baud rate adjustment?
• If not, is there a way to customize the BTS file to achieve this?
Our development is currently blocked due to this issue, and we would really appreciate any guidance or information.
Thanks!
