How to work on the CC2541 1-2 Mbps Data Rates in BLE?

Other Parts Discussed in Thread: CC2541

Hello everyone! My English is not very good ...

I want to use in conjunction СС2541 with jpeg-encoder CX93510 on the SPI 4 MHz. I need to RF-translate it with the two images per second 30 kB each.

To do this I need a transmission 500-kbps, 1-Mbps, 2-Mbps Data Rates of CC2541.

This can be done by BLE mode or not?

Link http://processors.wiki.ti.com/index.php/CC2540_Data_Throughput leads to sad thoughts (((

Thanks!

The BLE data rate is fixed at 1MBps.

To use the other data rates you will have to use the CC2541 is it's proprietary mode.

Hi Igor

Could you share the CX93510 user's guide with me?

I intend to use it in my design, but can't find this manual in internet, even at Conexant site.

Thanks.

Hi Igor,

Have you considered using a dual mode (Bluetooth Smart Ready) device, such as CC256x? This could allow you to switch from BLE to "classic" BT (BR/EDR) for the bulk file transfer. As stated above, the BLE Stack does not support mixed BLE/Proprietary operating mode; you would have to enter/exit BLE/Proprietary to use the faster PHY rates.

Best wishes
