CC2640R2F: CC2640R2FRSMR not work properly

Part Number: CC2640R2F
Other Parts Discussed in Thread: CC2650

sdk 4.40

iar 8.32.1

using C:\ti\simplelink_cc2640r2_sdk_4_40_00_10\examples\rtos\CC2640R2_LAUNCHXL\ble5stack\simple_peripheral\

out of the box.

when I test on CC2640R2 board, works well, can adv, app can scan/connect.

then I add CC2640R2DK_4XS macro definition, define one LED IO for my CC2640R2FRSMR board.

I can scan and find it only in a few seconds after power on, can not connect. looks like adv stop and nothing more.

I test several cases:

static void SimplePeripheral_taskFxn(UArg a0, UArg a1) {

// Initialize application SimplePeripheral_init();

setIO(IOID_6, 1); here we can see LED on, so it can run to here

// Create one-shot clock for internal periodic events.

Util_constructClock(&clkPeriodic, SimplePeripheral_clockHandler, SP_PERIODIC_EVT_PERIOD, 0, false, (UArg)&argPeriodic);

Util_startClock(&clkPeriodic);//I add this line to make it start immediately sure.

but

//in SimplePeripheral_processAppMsg

case SP_PERIODIC_EVT:

setIO(IOID_6,1); //this line not work as LED not on

and

static void SimplePeripheral_clockHandler(UArg arg) {

spClockEventData_t *pData = (spClockEventData_t *)arg;

if (pData->event == SP_PERIODIC_EVT) {

setIO(IOID_6, 1); //this line not work as LED not on

why? how to fix?

I want to make a periodic event and can run something periodicly, like make the LED blink.

then I will add POWER_SAVING to see whether it keeps working.

where can I purchase a CC2640R2FRSMR develop board? with sample project for it. so can I start quickly.

I have spent too much time on the start.

Hi,

Why do you need to use BLE5 Stack? Do you use any BLE5 features?

Refer to this post below instructions 2 - 7 on how to bring up a custom board. You can use the CC2640R2F Launchpad board files to work for your CC2640R2FRSMR based board.

which post? BLE5 is better why not use.

This post. BLE5 Stack is big for CC2640R2F and you might encounter memory issues developing your application. So, if your application does not use or require BLE5 features don't use it.

I followed the post, main thing is comment out pin define in BoardGpioInitTable. no help.

step 2. Make sure you set the correct define for RF Front End Configuration at CC2640R2_LAUNCHXL.h, I do not know how. here the case should be CC2640R2DK_4XS.h, I found nothing related to RF Front End Configuration.

is watch dog related? it is disable by default right?

and, I found no GAPROLE_ADVERT_ENABLED and GAPROLE_ADVERT_OFF_TIME in the project, so it is different for sdk 4.40 than 1.40.

where does it start advertise and set the advertise time?

a working board and sample code is very helpful, if I can buy it somewhere.

Hi,

Can you provide a web link about that board. I have worked with CC2640R2F 4x4, 5x5, and 7x7 custom boards. The procedure at the E2E post works. Here is the RF Configuration define at CC2640R2_LAUNCHXL.h. If you set this wrong you will have RF problems. So you need to know the RF configuration of you board.

/*
 *  ============================================================================
 *  RF Front End and Bias configuration symbols for TI reference designs and
 *  kits. This symbol sets the RF Front End configuration in ble_user_config.h
 *  and selects the appropriate PA table in ble_user_config.c.
 *  Other configurations can be used by editing these files.
 *
 *  Define only one symbol:
 *  CC2650EM_7ID    - Differential RF and internal biasing
                      (default for CC2640R2 LaunchPad)
 *  CC2650EM_5XD    – Differential RF and external biasing
 *  CC2650EM_4XS    – Single-ended RF on RF-P and external biasing
 *  CC2640R2DK_CXS  - WCSP: Single-ended RF on RF-N and external biasing
 *                    (Note that the WCSP is only tested and characterized for
 *                     single ended configuration, and it has a WCSP-specific
 *                     PA table)
 *
 *  Note: CC2650EM_xxx reference designs apply to all CC26xx devices.
 *  ==========================================================================

I have defined CC2640R2DK_4XS for project, and thus in CC2640R2DK_4XS.h (not CC2640R2_LAUNCHXL.h as you mention) I can see it is

#define CC2650EM_4XS

attached is the file FYI

about the board, I buy it from a small company here, which does not have tech support at all.

if you can recommend some dsk board, will be good.

another information is that, when I build my old project in sdk 1.40 and no power_saving mode, the board can adv well, I can scan and connect to it from my app. in power_saving mode, it can hit 10ms timer for 5 times and then no more.

This is your CC2640R2F 4x4 board attached to a main board? The led is IOD_6?

Hi,

Were you able to make the migration work? Markel's procedure is sound and should work well. A few comments:

dsp999 said:
, I found no GAPROLE_ADVERT_ENABLED and GAPROLE_ADVERT_OFF_TIME in the project,

I see these symbols in both SDKs. If you want to learn more about advertisements on SDK4.40, please visit the Simplelink Academy at:

https://dev.ti.com/tirex/explore/node?node=AD4sGbaamTCyn0DvZgBAsg__krol.2c__LATEST

One additional aspect is that you may want to look into the migration guides to move your project from the old to the new SDK. Details are shown at:

https://dev.ti.com/tirex/explore/node?node=AAafBKylj8ra01461K-lnQ__krol.2c__LATEST

Hope this helps,

still struggling. why not send the sample project (include hex you have built) you have tested for me to test?

0 dsp999 over 4 years ago in reply to desouza

Expert 1495 points

BTW, I am not migrating project from the old to the new SDK. I am directly using 4.40 sdk sample project, only need it to work with CC2640R2FRSMR

0 dsp999 over 4 years ago in reply to Markel Robregado

Expert 1495 points

could you please share your sample project (include hex you have built) for me to test on my board?

for RF, it should be CC2650EM_4XS, right?

when I examine the CC2640R2DK_4XS.c file I find it use pins more than the chip has. attached is the snapshot. is that problem?

Guru 86755 points

Hi dsp999,

If you use the CC2650_EM define it does not mean you need to use CC2640R2DX_4XS board file.

Using the original ble5 simple peripheral project, Follow the steps 2 - 7. After that rebuild all and flash the hex file.

I think I have tried, but I can try once more.

about step 2, Make sure you set the correct define for RF Front End Configuration at CC2640R2_LAUNCHXL.h,

how?

At CC2640R2_LAUNCHXL.h change the CC2650EM_7ID to CC2650EM_4XS. After you have done all the changes enable hex generation and flash the hex file using SmartRF Flash Programmer 2. See, if it is advertising and your able to connect to it using IOS LightBlue App or Android nRF Connect App.

After doing that then try to turn on and turn off the led. See, pin interrupt example program to know how to turn on and turn off led.

have tried, no help. to avoid hardware problem, I bought a new module, verified it working well(adv and connect ok), then flash the hex I have built, the same result:adv only about 50ms after power on. this is my hex:

could you please help test is it working on your board?

how can I have a working sample project?

Are you sure this is not a timing issue? If the board does advertise, but fails to connect it could be a problem with the real-time clock (RTC).

It is not clear from what you are writing, but do you actually have any SW that works on your custom HW? Or did you verify the default SDK project on a TI evaluation board before trying to move to your custom HW.

Correct RF settings is not critical for basic functionality. To get the SDK project running on your HW the only things you need to do are to remove the IO pins you do not have and remove the init stuff that interacts with the external flash on the development kit. I would recommend you do only these two modifications and then see if it runs on your board.

If your board actually advertises, but fails to connect, you should sniff the BLE communication to figure out why. Typically it will be related to timing.

If the RTC timing is off, you can change the SCLK_LF source to 24 MHz XOSC in CCFG and see if that helps.

hereby I confirm I have done all you said.

1, I confirm the board is adv ok out of box, hardware is ok.

2, Tried either CC2650EM_4XS or CC2650EM_7ID

3, remove pin

const PIN_Config BoardGpioInitTable[] = { PIN_TERMINATE };

4, remove ext flash

//Board_initHook();

the result is not related to connect etc, it is that adv very short after power on, when you scan it a second time, can not found it. (detail check is that it runs about 50ms, refer to previous information of the post)

since this question has blocked us for a very long time, could you please make it easier by verify it and send me sample project and sample hex?

With which FW (SDK version, example, etc) is the board actually working? Is it provided by the module manufacturer?

From the picture you posted earlier, it looks like your module does not contain the DCDC inductor and capacitor. If that is really the case you must configure your FW to use internal LDO instead. See https://www.ti.com/lit/pdf/swra640 chapter 11.3 for details.

Have you gotten any documentation from the module manufacturer on configuration?
