CC2640R2F: When i disable the "-DPTM_MODE" flag in .opt file, have any method i can change to PTM mode?

Hello,

I have assigned an expert to help with this query.

Dear Jan:

     Thanks for your help!

     If you have any ideas or solution, please tell me~

Hello:

Have any update?

Thanks~

Hi desouza:

Thank you very much for the advice you gave me, I'm ongoing to implement following your advice.
But now I suffer a very strange problem, and I want to consult you.

Now I always set DPTM_MODE in the .opt file. I use a static global variable, and the value which is getting from the PIN_ID(6) by the API PIN_getInputValue();
When I running ptm_mode, I will pull high PIN_ID(6) first. When I running non-ptm_mode, I will pull low PIN_ID(6).
I use this variable to decide whether to run the SPP_doEnablePTMMode(). And i think the function SPP_doEnablePTMMode() is the key point whether can run into ptm_mode.

But I suffer a strange problem.
there are three situations, and I describe as bellow:
1. I pull high PIN_ID(6), and expect to run into ptm_mode. After I testing using HCI command, and HCI command can work. And the xxx.hex size we burn-in is 278KB.
2. I pull low PIN_ID(6), and expect can run into non-ptm_mode. I testing non-ptm_mode is fail. And the xxx.hex size we burn-in is 278KB.

3. I direct using judge statement if(0), and the code will not running SPP_doEnablePTMMode(). I testing non-ptm_mode is successful. And the xxx.hex size we burn-in is 264KB

Whether the strange problem is because my code size exceeds the "total nonvolatile memory"? cc2640r2f datasheet write total nonvolatile memory is 275KB.

Danny,

I can't necessarily tell why your logic is not working, but since I never saw a development that dynamically switched between PTM and non-PTM modes, I wonder if it is necessary to reset the device to make this switch. I will consult with some colleagues. 

The one aspect about .hex files is that their size on disk is not a reflection on their size in the device's memory. Hex files are text files in nature with additional characters such as the initial colon (:) sign, as well as CR/LF, etc.

So, to know the size of the binary, you can refer to the linker .map file and see the usage as shown below.

Hi desouza:

Thanks for your reply for correcting the flash allocation knowledge. About the PTM_MODE switch, if you have any news, please inform me.

Thanks!

Dear desouza:

     In PTM Mode, we want to use the HCI command via UART to set BLE. We have to do RF testing.

     In non-PTM Mode, we want to connect to Mobile Phone via BLE, and we hope we can send some specific command between cc2640r2f and Mobile Phone.

     According to your cognition, can you give me some suggestions, what kind of Flag is not necessary and I can remove it? 

     My project has the following Flag:

-DCC2640R2DK_4XS
-DCC26XX
-DCC26XX_R2
-DDeviceFamily_CC26X0R2
-DICALL_EVENTS
-DICALL_JT
-DICALL_LITE
-DICALL_MAX_NUM_ENTITIES=6
-DICALL_MAX_NUM_TASKS=4
-DICALL_STACK0_ADDR
-DNPI_USE_UART
-DNPI_FLOW_CTRL=0
-DMAX_NUM_BLE_CONNS=1
-DPTM_MODE
-DRF_SINGLEMODE
-DSTACK_LIBRARY
-DTBM_ACTIVE_ITEMS_ONLY
-DUSE_ICALL
-DUSE_RCOSC

Thanks a lot.

Danny,

I consulted with some colleagues and they mentioned it should be alright to make the switch between the modes. I then found the thread below that describes a very similar scenario.Take a look at it and see if it brings some ideas.

https://e2e.ti.com/support/wireless-connectivity/bluetooth-group/bluetooth/f/bluetooth-forum/903540/ccs-cc2640r2f-ptm-in-ble5_simple_peripheral_cc2640r2lp_app

At this point, I would double check to see if anything in the file mentioned in the thread above (icall_hci_tl.c) has to be modified to make the PTM mode to be dynamically switched.

I will keep looking for additional resources, but please give these a try.

Hope this helps,

Rafael

Dear Rafael:

     I check the stack and heap status by using the ROV plug-in. But all looks good. So up to now, I don't know why I cannot switch PTM and non-PTM.

    Do you have any good news about how to modify the thread (icall_hci_tl.c)?

    Thanks!

Dear Rafael:

We found some "#ifndef PTM_MODE" in  icall_hci_tl.c. I think these should be marked If we want to dynamic switch PTM and non-PTM.

Now we mark these "#ifndef PTM_MODE"，and rebuild the project. But we meet the following situation.

The size of .cinit is over the max hole:0x1000. Are there any files can adjust to fix this problem?

Another question: Are there documents for describing the flag functionality? If yes, can you offer me the documents?

Thanks!

BR Danny

Dear desouza:

     Have any update about this?

     Thanks!
