Nothing is easy.... Please refer to this thread for details on an old networking issue, which we SOLVED for that platform, but now I can't make the MM+ respond to commands. - Network connection IS established between network and serial console on MM+ - MM+ DOES echo commands, but ONLY after you press [ENTER] - You can type whatever you like and [ENTER], and the MM+ does nothing - Keystrokes are NOT echoed while typing at the > prompt. - Keystrokes show up as complete words when you press [ENTER] This is the result of the network connection and attempts to talk to it: 
# IP address is correct, so is port number. # TT is set to vt100 mode # Baudrate of console is 38k4, but have tried lowering to 9600 Slower baudrate of 9600, and changing that in the network module config also does not help - it is exactly the same. I don't get what the hell I am doing wrong...... I will now try connecting a different device to the network module to see what happens. Smoke makes things work. When the smoke gets out, it stops! |

UPDATE I have fixed the no-echo thing by changing Line-At-A-Time to off. The MM+ is now echoing back each keypress, but [ENTER] still does nothing and no commands are executed. Smoke makes things work. When the smoke gets out, it stops! |

Hi G, I personally find that Putty is much better to use than TT. It has many more things that can be tweaked and I have had more success with Putty during the last few weeks with BlueTooth and WiFi connecting to the MM console. There will be a tick box (or setting) somewhere in there to get the desired result. Look in the Terminal setup tab/screen - Im not at home at moment to give the exact detail but know there where things there to change from default. So try Putty if you can - it may just work with default settings. WW EDIT: Let me add that I have used TT to very successfully connect to the MM console via Telnet (ESP8266/HC05) & SSH (RPi).

@ Jim - You're a star!!!   
That was what was stopping it!!!!! Thank you, thank you, thank you. 
@ WW - I will check out Putty, as I have not used that before. Smoke makes things work. When the smoke gets out, it stops! |

Now this is not working anymore. Everything is setup fine in the router, but all I get is 'Connection refused.' no matter if I use the actual IP address of the 107 module, or if I use my public IP address. This was working fine before - enter in public IP and port number, and it would route it to the 107 module. That worked both here at the house, and remotely. Now neither will work. I changed from Vodafone to Spark(Telecom) just before Christmas. Perhaps they are being problematic with port-forwarding? Smoke makes things work. When the smoke gets out, it stops! |

Grogs, Make sure you only have one 'session' (i.e. connection) open. I one had a TT session open on another machine and spent a long time wondering why I couldn't connect (Connection Refused message) from another machine. Or maybe you have a session that wasn't quite shut down correctly - some WiFi modules need to be power cycled to restart afresh to escape out of the 'loop'. Good luck . . .

Thanks, WW. 107 module is hard-wired network, not WiFi, and TT auto-closes when the connection is refused, so there is only one instance of it running or attempting. I rang a buddy, and gave him the relevant details, and he too got the same 'Connection refused.' message back. All settings are identical to when it WAS working with Vodafone(and that same buddy could connect then too), so I think this is Spark blocking port 5000 - it might be restricted or something. I will ring them tomorrow and see if I can get some kind of answer as to if they have restrictions on port numbers. I know you can't use port 23 with Spark - for some reason they have decided to use the Telnet default port number as their email server, which is an interesting choice... I will keep you all informed. Smoke makes things work. When the smoke gets out, it stops! |
