CC2541 now released, including support for Bluetooth low energy and proprietary
I'm very proud to announce the launch of CC2541, TI's second Bluetooth low energy single-mode SoC IC. ICs and EMKs (modules that plug into the CC2540DK) are available now. CC2541 is quite similar to CC2540, here is a list of the most important differences:
As long as you don't use USB or I2C, CC2540 and CC2541 are 100% pin-compatible, including using the same values for the RF matching components, so it is easy to move back and forth between the two. On the software side, they are 100% compatible, as the BLE stack masks some minor differences in the radio interface. The latest version of the BLE stack has full support for both CC2540 and CC2541.
If you are unsure whether to use CC2540 or CC2541, here are some points to consider:
If none of the above apply, it doesn't matter which one you choose. If cost is important, CC2541 is priced slightly lower than CC2540.
Many aspects of the CC2541 were inspired from feedback we've received from CC2540 customers. If you have suggestions for features you would like to see in future ICs or software revisions, please let us know (either by commenting on this blog, posting on E2E, sending one of us a private message or email), we'd love to hear from you!
Hi, is it possible to run SimpliciTI on it?
I have been looking at adding a CC2541 to a handheld system I currently communicate with via USB. Adding BLE would give the device greater flexibility.
The problem is with the data sheet. I cannot find which pins to use to connect the CC2541 with either a UART or as a SPI slave device. Can you point me to a document that identifies the alternate peripheral mapping for the I/O pins?
No, we do not support SimpliciTI on CC2540 or CC2541.
You may want to post this question on the E2E forums, as I don't know the detailed answer and I don't think the apps engineers necessarily follow this blog.
I do believe that you might find the answer either in the CC254x User's Guide or in the BLE stack User Guide.
is it possible to transfer audio from BT module UART to Headset?
The CC2541 is a Bluetooth Smart/Bluetooth low energy device. It does not support A2DP or the Headset profile. You should look at the CC2560 or CC2564 for this.
