CC2541: using RF proprietary mode and BLE stack together

Part Number: CC2541
Other Parts Discussed in Thread: CC2543

Hi,

I am trying to get the CC2541 to be running the RF proprietary mode for TX/RX and BLE stack to do the broadcasting of advertisement.

I had the chip in a while loop "running RF proprietary mode for 1 sec and sleep the next 2 seconds before I run the BLE stack to do broadcasting of the advertisement".

1. After starting the BLE stack, is there any function that I can call to disable it? I find that after I start the LL task (ie. LL_init), I will have problem with my RF proprietary mode. In my RF proprietary mode, I have a RF timeout that is controlled by timer 2. I assume this is something to do with the timer 2 which the BLE stack is using and also the RF proprietary mode is using.

2. I am using BLE-CC254x-1.4.0 stack. In my compilation, I notice the T2_isr is called in the library. If I want to amend something in the T2_isr, is there any method that I can do so?

thanks

Hi Ky,

Are you only doing BLE broadcasting? Not entering connections? If so, you can achieve what you want without running the BLE Stack. It is quite easy to set up the radio to send BLE advertisments directly through the radio registers.

Cheers,
Fredrik

Hi Fredrik,

Yes, currently I am only doing broadcasting without the need to connect. I check out on swru191c1.pdf document but the description on setting up the BLE for broadcasting is very limited. Can you provide any link or code snippet about setting up BLE broadcasting (which radio registers to control the data field, advertisement channels, etc)?

thanks!

Hi Ky,

You can take a look at the SW available at the bottom of this page: www.ti.com/.../TIDC-MINI-BLUETOOTH-LOW-ENERGY-BROADCASTER

It is for the CC2543, but it will be quite similar for CC2541.

Cheers,
Fredrik
