CC2560B: Long Discovery Times on Windows PC

Stuart Baker

Part Number: CC2560B

I'm working with a customer who is connecting to this device with a Windows PC. The PC scans for the device and it can take anywhere from 12 seconds to a full two minutes for the device to appear on the list of devices once turned on. Using the same PC with other BT devices (possibly not using the CC2560B), the discovery time is pretty much instant.

The presumption here is that there are some parameters that can be tweaked. Do we have any suggestions for parameters that might be tweaked to improve the discovery time?

Thanks,

Stuart

Hi Stuart,

Could you please share the Bluetooth firmware logs of CC256XB starting from the device initialization?
Logger User's Guide : processors.wiki.ti.com/.../CC256x_Logger_User_Guide

Additionally, do you see this issue only with Windows PC? Or with smartphones as well?

Best regards,
Vihang

Vihang,

Thank you for your response. The customer is distracted at the moment with another issue and will get back to this in about a week. We'll post to this thread once we have more information.

Thanks,
Stuart
