Hi @stevedb
Could you check whether the following libraries are up to date:
Seeed_Arduino_rpcWiFi - v1.0.2
Seeed_Arduino_rpcUnified - v2.1.1
Seeed_Arduino_FS - v2.0.2
Seeed_Arduino_SFUD - v2.0.1
Also make sure to use the Seeed_Arduino_mbedtls in dev branch
Finally, make sure the Wio Terminal SAMD core is updated to v1.8.1
Let me know the result
Best Regards,
Lakshantha
