WIO Terminal Workbench 1

Hi, just received the WIO Terminal and trying some examples.
But I’m allready stuck with the wifi examples, trying to update the RTL8720 chip.
Any advice ? tnx :slightly_smiling_face:

May be try the 3 bins files in a folder instead of just in D drive?

Hi and tnx, unfortunately that didn’t change anything.
I have tested and there is a serial connection with the device (So UF2 is working)

Maybe the gui version ? where can I find it ?

OK I’ve restarted PC (helps sometimes :crazy_face:) but now I see a different error message

UF2 is started first , win says com 7 is open but …

Try COM7 instead of 7 ?

No that didn’t help, I also tried changing the port and disabeling security :roll_eyes:


** will try later today on a RPI and a laptop with w10 home*

From this image is that the uf2 is not uploaded for this error

May be try this using Powershell? I’ve tested on my windows VM and works fine for me :smiley:

thank you ! … I gave up yesterday after a few hours :sweat_smile:
but… I’ll try again :grin:

YESS !! :smile:

So after this firmware flash I immediate started the arduino IDE and uploaded the Scanning Wi-Fi Network Example Code

I think I have all the libs installed

but bad luck :grimacing: … have to read a bit more

anyway, thanx So far for your help

oops… forgot to flash to new firmware … i’ll be back :rofl:

flashed the firmware

and … it works !

lesson learned, sometimes the connection (UF2 method) breaks So make sure you have a connection with the device

I just followed this example code Reading Coronavirus COVID-19 Live Data using Wio Terminal :wink:

after updating the wifi core

easy connecting to a breadboard with RPI expansion board :sunglasses:


That’s a nice way. :wink::ok_hand:

wifi power consumption - 320 mA

Hi @BoRRoZ

You adapter board means you can follow this Audio wiki also! https://wiki.seeedstudio.com/Wio-Terminal-Audio-Overview/

trying to interface a plantower pms5003 on a new sercom uart to create a mobile air quality device.

but I’m new to sercom and its complicated
I found this code snip (not tested yet) … it should create an uart but you can’t use I2C at the same time … is that possible I2C + UART on the grove connectors at the same time?

sercom left grove uart snippet
static Uart SerialPMS(&sercom3, PIN_WIRE_SCL, PIN_WIRE_SDA, SERCOM_RX_PAD_1, UART_TX_PAD_0);

void SERCOM3_0_Handler()

void SERCOM3_1_Handler()

void SERCOM3_2_Handler()

void SERCOM3_3_Handler()

And what is the max current ? on the grove connectors 3v3 line if you connect devices/sensors, I couldn’t find that info
