DA16200 MQTT DPM (reopened)

Hi,

Thanks for the support.

From the testing i had from my end I could find at some time (say 1-3 times when tested for 12 Hrs) the DA16200 module wake up from DPM and accordingly wakes up HOST MCU without any message received .From the debug log i could find some error log from DA16200 ">> ASSERT StackOverflow:mqtt_sub 318 !!!" what does this indicate?

Thanks

Hi Prem Sai, 

This means that stack size should be increased. Please try to increase the stack size - refer to section 9.1 Find/Optimize Stack Size for Your Application 

https://www.dialog-semiconductor.com/sites/default/files/2021-12/UM-WI-…

Did you solve the wake up issue?

Hi,

"Did you solve the wake up issue? "

>>From the testing i had from my end I could find at some time (say 1-3 times when tested for 12 Hrs) the DA16200 module wake up from DPM and accordingly wakes up HOST MCU without any message received.

"This means that stack size should be increased. Please try to increase the stack size - refer to section 9.1 Find/Optimize Stack Size for Your Application"

>>Is there any AT commands for doing the same?.This is shown when I've used "SDKV3.2.2.0_MQTTPING.zip" and not when "DA16200 DA16600 FreeRTOS SDK Image v3.2.2.0" used.

Thanks

Hi Prem Sai, 

Please find attached the newly generated image (SDKV3.2.2_MQTT_stacksize.zip) with increased stack size ( from 320 bytes to 1024 bytes). 

We ran it on our side and can not see the stack size overflow related message so far. 

If you still get the error message, please get the information for stack size and increase it accordingly. 

In the meantime, please find a diff file with the changes should be done in the SDK v3.2.2.0. You could apply this modifications in your SW, build the project and genarate your own image.

Question : can you please let us know which functions are you currently using on your project?

Hi,

Thanks for the detailed support.

I've used  SDKV3.2.2_MQTT_stacksize.zip and so far the issues are clear.Interrupt is received only when message received via MQTT.

Question : can you please let us know which functions are you currently using on your project? 

>>> Currently we are using only AT commands to do the following functionality

>MQTT for IoT.

>DPM mode and as Wake up source of HOST MCU.

Thanks

Prem Sai

Η Prem Sai, 

Gald that is working. With regards to your follow up question, please refer to the diff file. The example that with all the modifications has been shared with you.
