Strange things on upload program to RBL CC3200 Wifi Mini using Energia

[sufiaji 0]

Hi All,


This is my first post on the forum so apologize of any mistakes. So, yesterday I bought Redbearlab CC3200 Wifi Mini from Amazon. The out-of-box test successfully executed with the LED toggling on/off based on the button pressed on 192.168.11. But when I tried to upload the program using Energia, it was failed. Here is the message from Energia which I copy and paste it directly.

Ubable to find RedBearLabs board: 1
Using HID to reset for RedBearLab board

I am using Eenergia-0101E0017. I have followed the "getting startup guide" from Energia, pay attention closely to the driver and check the COM port (mine is COM40), also have updated MK20 firmware. But still, those error occured. And this wasn't the end of story....

 

After that, I put my laptop to sleep, went to office, turned on my laptop, and I used the same USB port to charge my android phone. 8 hours later, I put my laptop back to sleep, went to home and then I turned back on my laptop.This time, I tried again to upload my Wifi Mini using Energia, and boom, Done flashing successfully.

 

So until now, if I have a problem "failed to upload" using Energia, I repeat those steps:

1. make my laptop sleep.

2. wake up my laptop, connect android phone to the USB port.

3. make my laptop sleep again.

4. disconnect my android phone from USB port.

5. wake up my laptop.

6. connect wifi mini to USB port, open Energia and start flashing. Done.

 

So, anyone have the explanation about this?

 

Thank you.

Hi @@sufiaji

 

I haven't seen that error. But have you tried just unplugging and then replugging the USB (both sides) without the intermediate steps? Or try a different USB cable?

Hi @Mention,

 

Thanks for your reply. I will try and update here. Until now I haven't had the problem since. Maybe after I restart laptop later.
