  Interesting but I'm seeing the same thing from all 3 units now. I'll go over the hardware again as you recommend, maybe I messed something up.

  Not sure what's up now but I'm just getting gibberish:

  >Uncaught No 'ready' after AT+RST
    at line 2 col 18
     if (err) throw err;
  
   in function "a" called from line 1 col 100
   ...a("No 'ready' after AT+RST");else return b}
  
  in function "b" called from line 1 col 16
   {c=void 0;b&&b()}
  
   in function called from system
   Disconnected
  

  I added a cap (47uf) to the pads on the shim and it is still the same. I don't understand why the change in behavior...

  Hmm, neither changes the result. I did manage to get it to connect to an AP even though it wouldn't show it in the list. Guess it's time to dig into the code.

  Yes, I did try to connect to two different known APs and both failed.

  if I enable the debug output I get:

  APs: []

  so I'm seeing both a wrong syntax error at the top (right after printing the version) which looks like it is in response to AT+RST (though there is also an OK so I'm not sure of that) and an ERROR in response to AT+CWLAP

  BTW, I just soldered up another one and it does exactly the same thing.

  So I finally got my ESP8266 soldered to my pico using the shim and am having a couple of issues but the one I can't get around right now is that it won't see any APs even though there are at least 10 available in my immediate area. Here is the code I'm using:

  Serial2.setup(9600, { rx: A3, tx : A2 });
  var wifi = require("ESP8266WiFi").connect(Serial2, function(err) {
    if (err) throw err;
  /*  console.log("turning on debugging");
    wifi.at.debug(); */
    wifi.getVersion(function(err, version) {
      if (err) throw(err);
      console.log("version = " + version + ", resetting wifi");
      wifi.reset(function(err) {
        if (err) throw err;
        wifi.getAPs(function(err, aps) {
          if (err) throw(err);
          console.log("APs: [" + aps + "]");
        });
      });
    });
  });
  

  and I get the following output:

  version = 0018000902-AI03, resetting wifi
  APs: []

  I also tried using my phone as a mobile hotspot and placing it immediately adjacent to the antenna in case it seemed like an antenna performance problem. Any ideas?

  Thanks for the help. I figured out why it used to work, I was using a USB cable that had a bad data line which I needed to swap out to do the firmware update. With the old cable it works fine.
