Hi there,

and Welcome here…

So a couple things, the first would be SLOW down. Don’t be so quick in your actions and throw the kitchen sink at the thing :smile:
You can connect that board to the Serial port of the computer first!
Try to establish a connection using the AT commands. (PASS/FAIL)
Your kind of mixing the IP connection stuff with the Data LINK establishment first.
Did you LOOk at the wiki? for it.

LOTS of info on it…

USB Driver

The driver method used by 780E is the USB serial driver officially recommended by Microsoft . As long as this method is used, driver-free installation is possible, making it convenient for users to develop projects.

  • The USB driver does not need to be installed. After plugging into the computer ( 780E needs the powerkey to be grounded for 1.2S, VBAT power supply 4.2-3.3V, the USB port is connected to the computer, the USB cable is a data transmission cable, not a charging cable, the difference is whether there are DM and DP in the cable. A very convenient verification method is to insert the C port into the mobile phone and see if the computer pops up a large-capacity storage device. If it pops up, it proves that the cable is a data cable. Otherwise, the cable can only be charged, that is, there are only VCC and GND ) the following virtual ports will be displayed: the first two ports 81 and 82 can be used to send AT commands, and the corresponding port 83 is the LOG port (it may also be that the first two ports are LOG ports, which has been tested in practice).

Power is the big issue, it takes a LOT of it… to establish a connection then it’s a lot less but initially you’ll need a big cap or a big supply. :+1:

I wouldn’t bother with the USB port, use the serial port and terminal program, because your XIAO stuff will use it too.:+1: Get it going on the bench first then deploy to the Xiao otherwise you’re just waxing your carrot. :sunglasses: :ok_hand:
