Samsung S5 hotspot (Android)

Troubleshooting
1

Hi,
I have a Photon that works like a charm, but it’s impossible to use my phone as the Wifi connection. Using a shared internet connection other mobile phones it works well, but on my Samsung Galaxy S5 (SM-G900F) running Android 5.0 I can’t get a connection.

Here’s the output I get setting it up with “particle serial wifi”

? Should I scan for nearby Wi-Fi networks? Yes
? Select the Wi-Fi network with which you wish to connect your device: JCB7
? Should I try to auto-detect the wireless security type? Yes
> Detected WPA2(PSK/AES/AES) security
! Something went wrong: Serial port closed early

It’s not very likely that a serial port does “close early”, but I presume there’s ways to get proper information about that is actually happening?

Try to provide your WiFi credentials manually (answer “? Should I scan for nearby Wi-Fi networks?” with N).

If have a tool like inSSIDer you could check what band/channel your phone uses and if this is compatible with your Photon.

Have you maybe set access restrictions under “Allowed Devices” on your hotspot?

I think I found a bug. My phone is WPA2 Personal and when I connect manually I get this error:

? Security Type WPA2
/usr/local/lib/node_modules/particle-cli/commands/SerialCommand.js:745
			if (securityType.indexOf('AES') >= 0 && securityType.indexOf('TKIP') >= 0) {
			                 ^

I’m on OSX v10.10.5 but that’s probably not relevant.

What versions are you on? particle --version and node -v
Have you recently done a npm update -g particle-cli?

I’ll wait for my daughter, she’s got a S5, then I can try out

But meanwhile you could also try to connect with CoolTerm and send “w” that’s another way to provide WiFi credentials to the device (in Listening Mode too).
