Hi,

I wish to have both bluetooth and wifi capabilities in my project.

I am using TI CC2541.

Can I connect CC3000 to it ?

Hi Swarika,

it is not possible to connect a WiFi device with a BLE device. You will not be able to connect your CC2541 with a CC3000.

Best regards,

Hi Johan,

Thanks for your reply.

Can you suggest some other way through which I could have both wifi and ble on the same device.

Bluegiga seems to have achieved it somehow by using TI CC2541 because I saw a bluegiga module having both wifi and ble and it was using CC2541.

Please advise.

Thank you so much in advance.

Hi,

sorry, I think I misunderstood you question.

It is possible to control a CC3000 from a CC2541 using SPI.
This mean that you can have both a CC3000 and CC2541 on your device, thus having both BLE and WiFi in a system-on-module solution.

Best regads,
Johan

Hi Johan,

Could you please elaborate more on this topic?

Please tell me initial steps on how to connect both these chips together?

I have breakout board for both CC3000 and CC2541.

Thank you,

Hi Swarika,

The actual connection between the two chips are done using the SPI interface.

I really recommend you to start by looking at the CC3000 wiki page:
http://processors.wiki.ti.com/index.php/CC3000

I think you will find a lot of answers there!

Best regards,
Johan
