Unfortunately, I have to report that the bt library is totally broken in wiced-studio-5.0 release.

Below is the log, shows the buffer usage keep growing until out of buffer.

My application only calls wiced_bt_ble_observe(WICED_TRUE, 0, myr_scan_results_cb).

Note, it was working on WICED Studio 5.0.0.26 (Pre-Release).

Any chance to provide an urgent fix?

My platform file has a (wrong) WICED_BT_PIN_RESET setting.

It looks like older bt library complete ignore that setting (so it was working in older sdk).

With latest sdk, I just comment out that setting now.

hi mifo

As I said, we are waiting for official sdk for mass production.

With this issue, we just cannot use the official sdk-5.0.

It's a regression between  5.0.0.26 and official release.

I believe it should be fixed quickly by bisect to find the bad commit.

(It looks like a leak for the buffer usage)

Let me know when can I get the fix.

If you have problem to reproduce it, please let me know what I can help.

I hope the time is use in fixing real bugs rather than in figure out how to reproduce it.

My whole team are pending today to wait for your response.

1. Can you reproduce this issue now?

2. When will the fix availabe?

I need to know the schedule so I can arrange resource allocation.

I cannot make whole team waiting endless.

This is an urgent case, I hope we don't need to wait too long.

Hi Alex,

So far from what we tested, we could not see this issue. Can you please attach your code and logs here?

Hi axel.lin_1746341​,

I tested with the "ble scan test" file you posted.

When I ran the file, the logs stopped after some time and it crashed quickly as you said.

In the ble_scan_results_cb () function, when I replaced the "wiced_bt_print_cfg_buf_pool_stats ()" with simply "printf ("scan callback\r\n");" it was working fine. I was getting continuous scan callbacks without any crash.

The reason why wiced_bt_print_cfg_buf_pool_stats() could be causing the issue was it was printing lot of data after some internal processing, compared to simply printf. So there was a data mismatch between the rate of arrival of scan results and the rate at which the serial data is being printed.

When I added wiced_bt_start_advertisements() after the wiced_bt_ble_observe () API, i was still able to get continuous scan results (when wiced_bt_print_cfg_buf_pool_stats () is not used.

We recommend you not to use resource consuming APIs like wiced_bt_print_cfg_buf_pool_stats () inside scan callbacks, as the latter is being in quick intervals.

Please confirm this on your side and let me know.

regards,

Even you comment out the print and wait

You will still hit out of buffer issue

Hi mandy​,

I think your test is totally wrong.

Your log shows:

Starting WICED v5.0.0-RC5-5a014d3

so.. it is not official release.

As I mentioned before that in the pre-release, the scan work.

In *official* release, the scan has problem.

Below show you my log.

To make it clear, I comment out the wiced_bt_print_cfg_buf_pool_stats() call in scan_result.

(my scan_result callback is doing nothing now).

Below I print wiced_bt_print_cfg_buf_pool_stats() every 10 seconds in a seperate thread.

Test using official wiced-studio 5.0 release:

I also want to point out it actually fine to call wiced_bt_print_cfg_buf_pool_stats()

in the scan_result callback because It works in sdk-3.7.0-7 and 5.0.0.26 pre-release.

The only problem is "it's broken in official 5.0 release"

So can you reproduce the issue now? I'm still waiting for your response.

Hi axel.lin_1746341​,

I tested in pre-release #26 because, you mentioned that you observed the issue in pre-release.

This was your problem statement.

"Something wrong in BT library in sdk-5.0.0.26 pre-release.

Once start wiced_bt_ble_observe(), then calling wiced_bt_start_advertisements() will immediately got corruption due to out of buffers.

Note, it was working when using the bt library in sdk-3.7.0-7. It's a regression."

If you observe the problem is in the release version, we will check this and let you know shortly.

You totally mixes 2 issues.

Lets' focus on this one. As the subject line "BT library is broken in wiced-studio-5.0 "

This one is the most critical one.

Go testing use official 5.0.

Hi axel.lin_1746341

I tried with the official release and I still could not see any issue.

Our software team also tried the same and they also could not see any issue.

Please find the logs attached.

It's 100% reproducable here for ThreadX and FreeRTOS builds, so it must be something different between your seettings and mine.

Can you send me your BCM94343W_AVN platform file for checking.

Also can you tell me what is changed in BLE part between sdk version 5.0.0.26 ~ 5.0.0.33?

I figure out the problem now.

It's a bug in my platform file setting.

Thanks,

Do you mind sharing your finding in platform files? Appreciated.

My platform file has a (wrong) WICED_BT_PIN_RESET setting.

It looks like older bt library complete ignore that setting (so it was working in older sdk).

With latest sdk, I just comment out that setting now.

Hi axel.lin_1746341

I think I'm having the same problem as yours. I'm also using the BCM94343W_AVN and getting the same buffer corrupted messages. I have the WICED_BT_PIN_RESET set to NULL. But commenting out that line didn't change anything either. Is that what solved your problem?

I think you need support from cypress.

Good luck.

I've actually found a solution for this. I temporarily changed the number of buffers allocated for wiced_bt_cfg_buf_pools and downloaded the program to the board. That got rid of the buffer corruption. When I changed it back to the original number of buffers, there was no more buffer corruption either.
