I have same issue in my application. In my situation, I build with "ota2_manuf_download" option, and after that I can build with ota2_download. However, the program and DCT infomation is not updated after ota2_download and reboot.

In my understanding, after building ota2_download and reboot, the new application wake up. Is this wrong?

By the way, is libusbK USB Devices not problem as "WICED USB JTAG Port" in show above figure?

BRs,

Hiroyuki

I have an application that will receive infrequent commands over at TCP connection. I was wondering if there was a way to have a thread that handles the packet wake up at a packet reception event? The only packets it will receive will be commands, so the thread could wake up at any packet, not just TCP.

Follow up - is there an API to allow for explicit wakeup/send to sleep of a created thread?

Thanks!

iperf3 tests are run with UDP between 2 Pi 3B boards over the on-board WiFi ( channel 6 = 2.437 GHz)

Server Pi is set up as Access Point (hostapd/dnsmasq) and client Pi is attached.

Below is an example where iperf3 has zero data transfer for a full 1 second period (32-33 seconds).

Just prior there is high jitter with packet loss and after the event as well.

Test setup is running in a RF screen room with no interfering WiFi devices.

RF spectrum analyzer (2.437 GHz) shows complete loss of WiFi RF signal during this event - so Pi is not transmitting and nothing else is interfering.

Bluetooth is disabled on both Pi's.  Part is this chip:  https://www.cypress.com/file/298076/download

Does the CYW43438 periodically run calibration and shut down WiFi for 2 -4 seconds every minute?

Are there any kernel tasks in Raspbian that would shut down WiFi?  Can a log file be inspected to determine why WiFi stopped?

Can some parameter be changed in iperf3 (buffer sizing?) or in the WiFi configuration to avoid loss?

Or is there a known issue in the WiFi chipset or driver that could cause this loss?

It appears that iperf3 just hangs during this event - the stats do not reflect the gap, only the lost datagrams before and after.

Similar event is seen with WiFi TCP test - but only with Pi AP as client and attached Pi as server.

Reversing roles only has a few lower datagram rate events (loss), but never complete dropout.

Running the same test with a wired 100Mbps Ethernet connection yields 0% datagram loss (rate is 93.2 Mbps).

Any insights appreciated.

I am testing snip.httpbin_org on CWY943907AEVAL1F. I use WICED-Studio-6.2.

The original sample work correctly. I modified the  original source code to send data to my local server. I removed the CA check.

I can send small file (size = 300kbyte). but  I could not send a file that is over 400kbyte size.

Is it needed to change mbedtls/config.h ?

Need information for Callback registration for events like  Link/connection up/down , wifi hardware error,etc.

Can Event be registered in wiced  for wifi for particular events.

there are not many significant APIs to cover wifi events POLLING.

Any Alternative to handle situations of physical Events like connection error or hardware error.

Hi All,

I'm new to the Wiced devices. We are using BCM943907 device in our product.

I installed the WICED-Studio-6.2.1.2-IDE-Installer to my window 10 laptop and  imported existing code.

Send the " make snip.pers-BCM943907MERCIER-ThreadX-NetX_Duo-debug ota2_download " to create make file. but i'm receiving below error.

Please help me to resolve this problem.

CYW43907

FreeRTOS + lwIP

I have been using wiced_tcp_send_packet without any issues until i tried to send larger packets. I then switched to wiced_tcp_send_buffer and it works great in an example application with no TLS but once TLS is added and the packet is large enough to be fragmented, I run into a data_abort exception. The best that I can tell, the problem occurs in wiced_tcpip_common.c, at line 213, during the free call.

        if (enc_buf_allocated == WICED_TRUE)
        {
            free(enc_output_buf);
            enc_output_buf = NULL;
        }

Has anyone seen this?

The packet i was attempting to send was between 1800 and 1900 bytes.
