Start with RFM12Pi - nothing happens?

Hi all,

In the thread http://openenergymonitor.org/emon/node/2216 is talking about a German group. Now I do it in two languages. Page down the text in English
 
Nun dann fang ich halt einfach mal an mit dem ersten Post in Deutsch :-)
 
Ich bin neu hier und habe mir das RFM12Pi Modul 868MHz .
Damit möchte ich gerne die gängigen Temp-sensoren der.WS-9160IT (TX29-IT) auslesen.
Leider ohne Erfolg :-(

Ich habe:
- Raspi A+ (B und Banana auch)
- Raspian mit php, python, apache2 etc. und was man sonst so braucht 
- ttyAMA0 ‘freigeschaltet’
    cmdline.txt geändert
    /etc/inittab -> # T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100
 
Jetzt bin ich so vor gegangen wie unter: http://openenergymonitor.org/emon/node/3336
also mit minicom versucht eine Verbindung zu bekommen. Baut nix auf :-|
 
Kann es sein, dass RFM12Pi kein Prog auf der MCU hat (obwohl mit bestellt)?
Wie kann ich das rausfinden? Was kann ich noch probieren.

 I 'm new here and have my RFM12Pi module 868MHz. So I'd like to read out the popular temp sensors WS - 9160IT ( TX29 -IT).
Without success :- (
 
I use:
- Raspi A+ (B and Banana, too)
- Raspian with php, python, apache2 etc. and whatever we need
- ttyAMA0 ‘config’
    cmdline.txt changed
    /etc/inittab -> # T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100
 
Now I 'm done as under: http://openenergymonitor.org/emon/node/3336
So with minicom tries to get a connection. No connection : - |
 
Can it be that RFM12Pi has no prog on the MCU (although with ordered) ?
How can I find out ?
What else can I try?

Re: Start with RFM12Pi - nothing happens?

Hi all,

Now I'm able to connect to RFM12Pi on ttyAMA0.
I don't know what problem (program) makes it impossible. So I made a new Raspian SD-card - it works :-)

My settings:
Available commands:
  123 x      - Toggle configuration change protection, 1=Unlocked
  <nn> i     - set node ID (standard node ids are 1..26)
  <n> b      - set MHz band (4 = 433, 8 = 868, 9 = 915)
  <nnn> g    - set network group (RFM12 only allows 212, 0 = any)
  <n> c      - set collect mode (advanced, normally 0)
  ...,<nn> a - send data packet to node <nn>, with ack
  ...,<nn> s - send data packet to node <nn>, no ack
  <n> l      - turn activity LED on DIG8 on or off
Current configuration:
90 i26 g0 @ 868 MHz  Lock: 1

Next I expect, to receive all 868MHz devices in my room.
First the TX29IT Tempsensor:
f = 868,30 MHz +/- 30 kHz
Modulation: FSK
Frequenzhub: +/- 30 kHz
Transfer:  17.241 bit/s / 5 Bytes Data
Sync: 0x2DD4

I can't see sensor-data on minicom.
What should I do?
