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

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

ansonhe97 · September 21, 2020, 10:36am

Try COM7 instead of 7 ?

BoRRoZ · September 21, 2020, 10:56am

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

stuck4

** 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

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

YESS !!

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
22-Sep-20-10.03.47 AM

but bad luck … have to read a bit more

anyway, thanx So far for your help

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

BoRRoZ · September 22, 2020, 9:01am

flashed the firmware

and … it works !

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

Looking neat !

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

after updating the wifi core

BoRRoZ · September 24, 2020, 10:25am

easy connecting to a breadboard with RPI expansion board

salman · September 24, 2020, 10:41am

That’s a nice way.

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/

Or ethernet: https://wiki.seeedstudio.com/Wio-Terminal-Ethernet/

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()
{
  SerialPMS.IrqHandler();
}

void SERCOM3_1_Handler()
{
  SerialPMS.IrqHandler();
}

void SERCOM3_2_Handler()
{
  SerialPMS.IrqHandler();
}

void SERCOM3_3_Handler()
{
  SerialPMS.IrqHandler();
}

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

Changed the power unit to LiFePO4 6000 mA followed by a DC/DC step up 3.2v to 5 v and a charger module So I can charge the device with my phone adapter.
The PMS5003 needs 5v but data lines are 3v3 so no need for level shifter when connecting to the WIO terminal.
