Ultra Low Power Wi-Fi SoC for battery powered IoT devices


The DA16200 SoC is the world's first Wi-Fi SoC delivering year plus battery life for always connected Wi-Fi IoT devices. DA16200 is low power Wi-Fi networking SoC that delivers a dramatic breakthrough in battery life even for devices that are continuously connected to the Wi-Fi network. In most applications, one year plus battery life is achievable. There is no tradeoff in output power or range as the SoC’s range is industry leading. The chip also features very strong IoT security, including WPA3 and TLS for authentication and encryption at Wi-Fi and higher stack layers.  The DA16200 is a full offload device, meaning the the entire Wi-Fi and TCP/IP networking stack and even end product application code can run on chip with no external CPU or MCU required. Alternatively, a small inexpensive MCU can send the DA16200 commands and the SoC will still perform the full offload networking stack functions.     

The DA16200 modules are the perfect complement to the DA16200 ultra low power Wi-Fi SoC.

DA16200 - SDK threads crashing when using a HTTP server

Posted by l.wassermann 15 points 4 replies


I am using the Generic SDK for DA16200 and have issues with some threads causing a reboot of the system (umac_fc9k, WLANx_IP or http server thread).

The project mainly consists in a HTTP server hosting a graphical user interface. The HTTP server is configured as described in the documentation and uses the nx_http_server_web_open/close/get_size/get_payload functions to retreive and send the resources (HTML, CSS and JS files) requested by a client.

When browsing the interface on a web browser, it occasionally happens that a thread from the SDK (either umac_fc9k or WLANx_IP) or sometimes the HTTP server thread himself causes a reboot.

Here is the console log from when one of these reboot occurs :

[[OOPS Dump : c0f0]]

Wakeup source is 0x0

If this can be of any help, the size of the data handled by the HTTP server can reach about 15 kB.

I could not determine a specific way to cause a reboot. It seems to happen randomly when browsing the website. It also seems to only happen when the HTTP server is receiving requests from a client.

I am therefore looking for some technical support as it seems that I do not have access to the code of these threads (or else I could not find it).


Thanks in advance

Hi l.wassermann,

Thanks for coming and posting on our WiFi forums.

Can kindly versify the SDK Generic version? Is it version 2.3.0, as tagged in the initial post?

After that, I’ll escalate this question to our tech Team internally to check it out and get back to you ASAP.

PS : The latest DA16200 SDK generic version is v2.3.4.1. Are you able to replicate this?

Thanks, PM_Dialog

Hi l.wassermann,

We tried to reproduce the issue with the HTTP server sample code from SDK v2.2.3.0. However, we are not able to reproduce it on our side. It's not too easy to give some advice and check the oops log because we have only the oops logs.

However, according to the CFSR(- CFSR  :00000400 -), it looks like a memory corruption related issue. This might be the root cause.


There are some changes in HTTP server side in our source control system, but they are not major between SDK v2.2.3.0 and SDK v2.3.4.1. Additionally, many files have been disclosed in SDK v2.3.4.1 which is the latest SDK version.

In this case, we would suggest to debug it further or the issue might be solved by using the latest DA16200 SDK, v2.3.4.1.

Keep in mind that is strongly recommended to use the latest SDK v2.3.4.1?

To do so, can you kindly use the SDK v2.3.4.1 and test this again? Does this issue exist?

Thanks, PM_Dialog
