Hi Guys...

I'm trying my WeMos Clone and I'm always getting a time out error...

Here's my board:
ed0532e3d105c90af5a24072431d6d7d.jpg

I'm trying a very simple example derivate from one of EREL's examples, that in this case (should) just log the wireless networks in range SSID's

B4X:
Sub Process_Globals
  Public Serial1 As Serial
  Private wifi As ESP8266WiFi
End Sub

Private Sub AppStart
   Serial1.Initialize(115200)
   Log("AppStart")
   ScanNetworks
End Sub

Private Sub ScanNetworks 'ignore
   Dim numberOfNetworks As Byte = wifi.Scan
   Log("Found: ", numberOfNetworks, " networks.")
   For i = 0 To numberOfNetworks - 1
     Log(wifi.ScannedSSID(i))
   Next
End Sub

Please help!!

same as my woring settings for full size board, cannot see why it wouldn't work at that. Have you tried slowing down the upload speed?

can you write to it from arduino ide with same settings?

I haven't tried writing to it from Arduino ide because I cannot make sense of it... or find a simple enough sketch, like the above

From time to time, my error changes from a simple time out, to this:
exit status 1C:\Users\psapg\AppData\Local\Arduino15\packages\esp8266\tools\xtensa-lx106-elf-gcc\1.20.0-26-gb404fb9-2/bin/xtensa-lx106-elf-ar: unable to rename '\\RASPBERRYPI\Data\B6SOM5~D\B4R\ESP8266\Objects\bin/arduino.ar'; reason: Permission denied

So I decided to copy the folder to my D drive and it did compile... eventually! Timeout set to 280secs...
But nothing happens after the compile successful message... it's like the code is not executed

So I finally got it working... Seems like B4R does not like much working with remote locations...
I copied the project folder to my Local D drive, and re-set all the Board params to their default values and lowered back my timeout to 120..
All works fine!!

So you had the project on a network share and it wouldn't work. Interesting to know. I will have to keep a mental note of that one ;)

Good find @Cableguy
