LPSTK-CC1352R: HDC2010 drivers bug

It is not clear to me exactly what you are testing.

Are you saying that the default dmm_154sensor_remote_display_oad_lpstk_appf only works in the 3_40 SDK and not from any of the other SDKs, or are you doing modifications to the example?

I have LPSTK-CC1352R   which I'm flashing with oryginal example as advices in out of box experience

C:\ti\simplelink_cc13xx_cc26xx_sdk_5_30_01_01\examples\rtos\CC1352R1_LAUNCHXL\ble5stack\multi_sensor

When I compile code from above SDK  and program LPSTK   I'm not getting temperature and huminidity readings in   SensorTag application on the phone.

Additionaly if I use terminal to see what output I'm getting from LPSTK its like below

I found out that compiling orginal examples from below list has the same issue

simplelink_cc13xx_cc26xx_sdk_5_30_01_01
simplelink_cc13x2_26x2_sdk_5_20_00_52
simplelink_cc13x2_26x2_sdk_5_10_00_48
simplelink_cc13x2_26x2_sdk_4_40_04_04

and the only one which is working is example from this SDK: simplelink_cc13x2_26x2_sdk_3_40_00_02

Above issue might be very easy replicated by product manager of LPSTK-CC1352. 

I'm using  Code Composer Studio 10.4.00006 with oryginal not modified examples. No errors during compilation.

I will be very appriciated for help as I see more people might have this problem. 

I found out that other persons get the same problem  (+) LPSTK-CC1352R: Multisensor example does not show temperature, illumination - Bluetooth forum - Bluetooth®︎ - TI E2E support forums

and also here (+) CCS/LPSTK-CC1352R: cannot connect to LPSTK-CC1352R after re-flashing multi-sensor app - Bluetooth forum - Bluetooth®︎ - TI E2E support forums

In my case I cannot move to old simplelink_cc13x2_26x2_sdk_3_40_00_02   which I confirm it's working  because  I use newer  SDK in other custom example where I have exactly the same problem like with   orginal multisensor example which is provided by Texas Instruments.

It's looks like it might be related to problem with interruptions - as I2C clock line nevever go up.

Hardware is confirmed is working well as compilation example from older example confirm all works perfectly. Looking forward for help with that.

I will try to get hold of some HW and see if I can reproduce the issue. In the meantime, can you please try again and test the 5_30_01_01 SDK example, using the correct version of CCS? This SDK should be run with CS 11.0.0

I spend one week looking whats I'm doing wrong or what is the problem. I think I found reason why other people has similar problem and TI  was not solve this issue for so long. My advice is once you will try to replicate issue please  use  batteries  and turn on swich on LPSTK. Additionally I'm using Launchpad CC1352-P2  as debuger which I have connected pernamently to laptop (for debuging you cannot reset device by pulling USB plug from computer). Waiting for your feedback and findings with real equipment and example.

I have prepared video describing problem - I hope it will help to find solution to make possible debugging  https://we.tl/t-xmtlKI3jPb

Hi Michael

Someone more familiar with the multi sensor example and the sensor will look into this. Please be a bit patient, as responses might be delayed due to the Holiday Season.

Thank you very much for looking into this!

Michal,

Can you try the solution here: https://e2e.ti.com/support/wireless-connectivity/bluetooth-group/bluetooth/f/bluetooth-forum/974566/lpstk-cc1352r-sail-sensor-library-bug-in-ble5stack-multi_sensor-example 

Basically, remove sail.lib from the project and force it to use source files. 

Regards,

Daniel
