Wio terminal webserver fails after a few data exchanges

Trying to get Wio Terminal webserver working (from the Network/Advanced WiFi Usage section of Seeed’s Wio Terminal examples).

Altered the code so it displays messages on the Wio Terminal’s screen rather than to the serial terminal. Other than that code is the same as the example.

Http server starts up OK and links to 192.168.0.57. When typing “192.168.0.57/” in Google’s browser it connects for a few times and displays “hello from Wio Terminal !” then, for no apparent reason, the next time I get Google’s little timer circle and nothing else happens - stuck !

Looked on the forum and found there was a problem with the Seeed_Arduino_rpcUnified library so installed the latest version (from gitHub) on the Arduino IDE. Now nothing appears on the screen. No IP address no “Http Server Started” message - nada ! Changed back to older version of library and it worked OK again.

Any ideas on what the problems might be would be gratefully received.

Hi @apw1155,

We have recently updated the RTL8720 firmware and the Wi-Fi-related libraries:

Seeed_Arduino_rpcUnified - v2.1.3
Seeed_Arduino_mbedtls - v3.0.1
Seeed_Arduino_FS - v2.0.3
Seeed_Arduino_SFUD - v2.0.1

Please try again with the updates.
