Hi Everyone! I am developing on RTL8729DN (BW16), I have loaded an example “DeepSleepMode”. I did not edit it ![image](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/1X/b54eb7a9f44e3bbc3caf95ef9a4f84a650b8d60b.jpeg) But i did receive the unexpected result. ![image](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/1X/51cdfc8ff15eaea00ca06d3ce3496093d30d1712.jpeg) I use the hardware to connect WIFI “OK”. Please show me these miss! Thank you so much ! Thien. ---

Hi @xidameng! That example I downloaded into BW16. But it did not deepsleep. the result is in second scereenshot. I think if it is correct after 5 seconds is wakup 1 time. Thanks! ---

Hi @Nguyen_Thien [https://www.amebaiot.com/en/amebad-arduino-deepsleepmode/](https://www.amebaiot.com/en/amebad-arduino-deepsleepmode/) Please read this deepsleep example guide and understand that **ONLY** the following pins can be used for this feature ![image](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/1X/4f9d03b18e2a440cece7a2e5d27140e3dc0ae320.png) And unfortunately, due to design consideration and package, BW16 does **NOT** have all the pins that RTL8722DM has, so unfortunately, you can NOT directly use the example code written for RTL8722DM for your BW16. For more information, you may download technical documents from the official website at, [https://www.amebaiot.com/en/](https://www.amebaiot.com/en/) ---

Thanks @xidameng! I would like deepsleep mode in pins (BW16). Please Can you guide me to edit that example? Maybe edit BW16 hardware. Thank you so much. Thien. ---

Deepsleep is not really supported on BW16 if you choose to use Arduino IDE to compile binary, bcos deepsleep example need to change the bootloader but Arduino IDE only can edit the application firmware ---

Thanks a lot! @xidameng. So If i dont use Arduino IDE. is there any way to Deepsleep mode in BW16? Thanks again! Thien. ---

Hi. @xidameng. I see " Building the First GCC Project on Ameba-D" is a pretty difficult for me. If I use IAR IDE is it ok? There’s more , in Arduino IDE I have connected Wifi and BLUE ok. I’m afraid I won’t be able to do it. Can I still use the Arduino IDE after changing the bootloader? Because there is still Deepsleep in Arduino IDE example. Please help me.I wish you a good day! Thien. ---

Wow! it’s really cool. Im going to use the Arduino IDE after changing the bootloader. Now what do i do with the bootloader? Im downloading IAR… ![image](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/1X/2095cddb8219debc6e86338213635ed0f25e7780.png) Thien. ---

Hi, @xidameng Can I use “ImageTool\_v2.3.2\_AmebaD” to download BW16 through Uart? ![image](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/1X/a417cd58befae1b0bd477f515abbd477954dbd2c.png) I have only “Silicon Labs CP210x USB to UART Bridge” tool or ST-link V2.

yes you can! make sure to download all 3 “bin” files and tick their boxes, and press button on board to enter Uart Download mode before you click the download button ---

hi. @xidameng After install and i built all Project\_hp\_release and Project\_lp\_release. Then downloaded into BW16. The program worked. But now I don’t know how to proceed. Another thing is that I see in the program there are two pairs: Bootloader(KM0), main.c(KM0) and Bootloader(KM4), main.c(KM4). I don’t know how they work? Thien. ---

Hi @xidameng I have done Deepsleep mode already. I tried to implement the available example but it didn’t work. how do i execute an example “BT\_CONFIG”? ![image](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/1X/e14055ea62614594b900b1ff2ea2483193b27f8b.png) Please help me!

Hi, what matters here are only 3 binary files, namely, km0\_boot\_all.bin (small core’s bootloader), km4\_boot\_all.bin(big core’s bootloader) and km0\_km4\_image2.bin(your application program which contains programs in main.c) ---

> [@Nguyen\_Thien](#): > > how do i execute an example “BT\_CONFIG”? There are two ways to play BT\_CONFIG, 1. Use Arduino IDE, go to example and look for BLEWiFiConfig 2. Use Standard SDK and follow instructions on the application notes under Bluetooth chapter to set up the environment and then check out AI-Thinker’s website for their instructions on how to use BT Config, links are as follows, [https://github.com/ambiot/ambd\_sdk/blob/master/doc/AN0400%20Ameba-D%20Application%20Note.pdf](https://github.com/ambiot/ambd_sdk/blob/master/doc/AN0400%20Ameba-D%20Application%20Note.pdf) [https://docs.ai-thinker.com/en/rtl87xx](https://docs.ai-thinker.com/en/rtl87xx) ---

Before I have played BLEWiFiConfig example on Arduino IDE. But having Deepsleep problem. Does the Standard SDK have to follow the “29.2.2 IAR Project” steps? ![image](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/1X/414f8a810f8df465e7bb60cd5181e89ce6ece1db.png) Thanks!
