Combination kaku and somfy

#1 Post by gdroos68 » 01 Feb 2018, 12:43

Hi, I have an original rflink with aural tranciever. As expected is the reception of kaku signals really bad but sending is OK. In the past I used a cheap Chinese receiver for kaku. Can I disconnect the receiver part of aural and use the Chinese in stead? Which pins should I disconnect?

Aurel is good. You should not have any issues with KAKU. (or do you mean Somfy as in your title?)

Sorry, I forgot to mention that I have the rflink for somfy frequency. But the reception of Kaku signals is really bad. Only about 20cm. Sending to Kali seems OK.

In that case you can experiment with different receivers/transmitters..
Wiring is explained here:

Sorry but I am a bit of a noob: which pins of the aural should I NOT connect?

I thought you wanted to remove the Aurel and put some other module on it..
Btw, if you have a print with the Aurel, you can also remove the entire print and just connect a different module with wires to the arduino.

Basically I want a combination of both. Maybe a more elaborate description of my intention:
I bougth the 433.42 RFlink pcb including the aural transmitter to control my somfy. However the receiver part is really bad for 433.92. As stated in a post before, I only have a range of about 20cm. My idea was that i use the rflink pcb but only connect the transmitter part of the aural and use a chinese 433.92 (which has worked quite good before) receiver. I am still in doubt how exactly: either by not soldering the relevant receiver pins of the AURAL to the pcb or not soldering the relevant PCB pin's which connect to the arduino.
I have found the following wiring schedule:
Aurel RTX MID 5v:

If you would like to use the Aurel RTX MID 5v Transceiver the pinout is:
Pin 1 = Antenna
Pin 2 = Ground
Pin 3 = Not Connected
Pin 4 = MEGA tx3/Pin 14 (TX Data)
Pin 5 = MEGA rx3/Pin 15 (-RX/TX- toggle signal!)
Pin 6 = MEGA Pin 22 (TX Enable)
Pin 7 = Ground
Pin 8 = optional: 20k resistor to ground
Pin 9 = MEGA rx1/Pin 19 (RX Data)
Pin 10= MEGA VCC (Also connect here a 100nf to ground)

Incase of disconnecting AURAL pin's to the PCB: Which pin's should not be soldered?
Incase of disconnecting pcb to arduino: which MEGA pins should not be connected?

Thx for your patience. lol
