DA16200 abnormal DPM

Hi,

I've been using DA16200 Mod and usings its AT command as an interface with the HOST MCU.

When the DA16200 MOD goes to DPM and when the Wi-Fi is disconnected, what we are expecting is the default configuration like

"""

60, // 1st Wakeup

60, // 2nd Wakeup : 0xdeadbeaf is no wakeup

60, // 3rd Wakeup : 0xdeadbeaf is no wakeup

60 * 30, // 4th Wakeup : 0xdeadbeaf is no wakeup

60 * 30, // 5th Wakeup : 0xdeadbeaf is no wakeup

60 * 30, // 6th Wakeup : 0xdeadbeaf is no wakeup

60 * 60, // 7th Wakeup : 0xdeadbeaf is no wakeup

60 * 60, // 8th Wakeup : 0xdeadbeaf is no wakeup

0xDEADBEAF // 9th Wakeup : 0xdeadbeaf is no wakeup

"""

is this default config.

We encountered a scenario in which the DA16200 MOD wakes from DPM scans for Wi-Fi and goes to DPM with a periodicity of 13-14 second.

Our project is batterry operated and because of this battery drains rapidly.

DA16200 LOG has been attached where i could find wake up source as 0x90 what i was expecting was 0x82.what does this 0x90 represents i couldnt find it anywhere.

  • Hi Renesas support team,

     I will be communicating with you now onwards on behalf of Prem Sai regarding any clarifications you need in order to solve this issue,

    As for your question, We are using a custom board. 

    Thank you so much for your prompt responses.

    Regards,

  • Hi Nandagopal,

    Thank you for the confirmation. We are working on this and will get back to you.

    Best regards,

  • Hi Nandagopal,

    Our team internally has tried to replicate this issue using an evaluation kit for the DA16200MOD with no success so far. The device on our side is running and waking up as expected.

    The interval for 0x90 wake-ups on your side is about 15 seconds. Is it possible that there was some process that the MCU was doing during that time?

    Please also check below chapter 4 on Abnormal DPM operation

    https://www.renesas.com/kr/en/document/mas/um-wi-005-da16200-da16600-dpm-manager-user-manual?language=en

    Could you please share the following information:

    1. A description or schematic of the hardware connections between the MCU and the DA16200MOD that is also showing the GPIO pins used.

    2. If you have made any other changes that you haven't mentioned above.

    3. UART1 and UART0 (DA16200 console log) logs with timestamps.

    Best regards,
    AA_Renesas

  • Hi Renesas Team,

    Thank you for the continued & prompt support.

    Is it possible that there was some process that the MCU was doing during that time?

    Answer: The Host MCU is in sleep mode most of the time. The Host MCU is only woken up by the Dialog Module via an interrupt signal when an MQTT Message is received. 

    For this particular issue , The Host MCU is in sleep condition the entire time and hence not involved. This issue is isolated within the Dialog module itself. 

    I will share the GPIO Schematics soon .

    Thank you once again,

    Regards,

    Nandagopal

  • Hi Nandagopal,

    Thank you for your answer. Please let us know with the rest of the requested information (GPIO, schematics, UART logs) when you can.

    Best regards,
    AA_Renesas

  • DA WIFI MODULE.PDF

    Please Find Attached GPIO Schematics. If you need any clarification regarding the schematics please let me know

    Thank you for your prompt & consistent support

    Regards,

    Nandagopal

  • Hi Nandagopal,

    Thank you for sharing your schematics and for your offer for additional information. Would it be possible to also share the  UART1 and UART0 (DA16200 console log) logs with timestamps as requested above?

    Best regards,
    AA_Renesas

  • Hi Renesas team,

    I will try to get you the UART Logs. This log was uploaded at the start of this query by Premsai. Does this help in any way?

  • Hi Nandagopal,

    Thank you for your answer. While this log is useful it would be very helpful if you could also share the log from the second UART interface too (we need both UART0 and UART1 logs when the erratic behaviour occurs). This could potentially help us better pinpoint the origin of the issue.

    Best regards,

  • Hi Renesas team,

    I was made aware  that only the above submitted UART log was recorded during the occurrence of this issue. The same firmware was flashed again and factory resetted using the Multi downloader tool for Dialog and we were unable to recreate this issue again as of now.

    Regards,

  • Hi,

    Currently we are using "SDKv3.2.2.0" with the changes done by DIALOG.

    Ref:https://renesasrulz.com/wireles-connectivity/f/wi-fi/20024/da16200-mqtt-dpm-reopened

    SDK Image : SDKV3.2.2_MQTT_stacksize.zip

    If we use "SDKv3.2.4.0" these changes might not be present is it possible to provide the updated SDKv3.2.4.0 image with the necessary changes. 

    Thanks

    Prem Sai

    Hi Renesas Team

    Would it possible to provide the updated SDK v3.2.4.0 with the necessary changes that were made by the Dialog Team?

    The Reference link will  give info on the custom changes that were made by Dialog to the SDK v3.2.2.0 for our requirement , so that you can repeat the same changes in the latest SDK.

    Thank you for your constant support!

    Regards,

    Nandagopal
