Hey Baozhu,
I work with @wernervor. We have experience with the ‘network’ module in MicroPython on the Pycom boards, which use an ESP32. Both the WiFi and BLE API through the ‘network’ module work pretty well. In the meantime, we are trying to develop using the Arduino IDE to test out the WIO Terminal, but it seems like the Seeed WiFi libraries are still under development as well. I am following the wiki, after updating the RTL8720 firmware, but still getting compile errors from the WiFi libraries.
Thank you for your help!
