LP-EM-CC2340R5: Dynamic broadcast will enter a dead loop after 18 minutes of execution.

Part Number: LP-EM-CC2340R5
Other Parts Discussed in Thread: SYSCONFIG

Hi Team，

In other cases, please refer to the relevant questions

I tried your suggestion and set fixed 6 seconds broadcast by SYSCONFIG.

, and successfully changed it to be able to dynamically drop packets. But still...it will stop in the same dead loop after about 18 minutes.

However, he continues to broadcast the same old packet. But all actions stop in the FaultISR() loop‧

I modified the method as shown below:

Added a new event "BLEAPPUTIL_ADV_START"

Execute Fornat_ADV();

This FUNCTION is the "Advertising Task 2 – Change the Advertisement Data" mentioned earlier

Change the packetization method as described.

Best Regards，

Hi Galaxy,

Can you please provide more details about the "Format_Adv" function?

Please also consider reviewing the following piece of documentation https://dev.ti.com/tirex/content/simplelink_academy_for_cc23xx_7_20_01_00/_build_simplelink_academy_for_cc23xx_7_20_01_00/source/cc2340rx_02_ble_scan_adv_basic.html#id7

Also, in order to reduce the possible root causes for this issue, I would recommend to try to only enable the advertising (without changing the data) and see if the crash happens after 18 minutes or not.

Best regards,

Hi Clément，

I seem to have found the problem.

When I try to put "uint8_t *advData2 = ICall_malloc(ADV_DATA2_LEN);"

After declaring it as a fixed array variable, the 18-minute crash will not occur.

Thanks for your help.

Best Regards，

Galaxy
