There is a peculiar behavior observed in our application.
I have been investigating the WiFi initiation and connectivity issues during bootup with a legato app initializing WLAN1.
Issue under discussion is at
Once the Application starts, connectivity to external IPs is lost (ex. a ping command to GoogleDNS, etc). Our app is expected to send a file to an external host.
After a step-by-step review and troubleshooting, found that a call made to reset UC IOT card through GPIO2, is the culprit. After the call, all TCP transactions from the mangOH red are stopped. And it’s not recovered until reboot.
Did anyone come across similar issues? Is there an explanation and possible solution to this?
Thanks in advance.
