856  Using Arduino / Networking, Protocols, and Devices / Re: arduino IDE serial not sending carriage return still ?? on: September 24, 2012, 05:53:37 am
I just tested the SM20 range, at 9600 baud, and the transmitter on the front of my car ( bonnet/hood :-) ) and my son walking down the tree-lined road with the receiver ( with a flashing light ), so the height was about a meter off the ground.

Both antennas were actually too long ( I forgot to trim them ) at 185mm ,  and the reliable range was 500m , which is fine for my needs.

I will however set up the SSI ( now that I can command the modules ) and trim the antennas for max signal,  and try it again, just out of interest.

"Still no Australian flag though, people might get the wrong idea and think I'm a Pom*

Thats because you post in English Rob, try your next post in Australian, and see if the flag changes :-)

OK, I did it with v22 by using below.  I copied bits from other posts, and this works.

I am really impressed with the SIM20 transceiver - especially now that I have hooked them up with Bill Porters EasyTransfer library -  what a pleasure.
By setting the AT commands below, the modules current drops to 30 microaamps after 2 seconds of no data in ( I am only using this feature on the remote control end because of battery life )

They reckon over half a kilometer range, so I am going to hook up batteries onto my 2 arduino boards, and go and see for myself .
Code:
 digitalWrite(AC2DPin, LOW); //command mode
   delay(120);
 SIM.println("AT+SRDEPS=1");
  SIM.print("\n");
 digitalWrite(AC2DPin, HIGH); // data mode

Just bought a Samsung 60" 240Hz refresh LCD TV.

60"  !!!    The eyes are finally going then Crossroads ?   Thats bigger than my lounge :-)

I just added myself, I zoomed in on my house and clicked "add yourself"  and low and behold it put me downtown Cape Town near the popular drinking holes of the Waterfront  -  perhaps its an omen and I will be able to retire soon ?

IC sockets are handy, but dont like being soaked in conformal coating, its Hobsons choice like having a Molex plug. These units are for tropical Africa and I dont want them corroding......

Well the 35 replacement chips should arrive tomorrow, so I spent a couple of hours on every electronic guys favourite job,
desoldering 700 legs to remove the dead chips,
Sore eyes,   sore thumb ( from arthritus and a solder pump ) ,  I do hope the guy doesnt reverse the supply again,  GRRRR   :-(

I bought $150 ( I think it was ) worth of chips from Mouser to qualify for worldwide free shipping,  but I still had to pay about $30 handling fee this end ( South Africa ) to get that same size box as your photo.

I have had to leave it for now,  the fan is muckspreading today,  but what I was trying to do is use the arduino boards USB to TTL.

The big surprise for me is how the number of idiots has steadily increased the past 40 years.

I refuse to be drawn into discussions about the South African Government  :-)

"for $50,000, you can buy one directly from the designers" That seems like a steal, I think the price is only valid if resident in non-city regions of Africa. smiley-cool

Its not such a steal here,      dont forget that $50,000 here in Africa could buy you a house !  or 10,000 restaurant pizzas !  or 14,000 quaffable bottles of wine.

 but I drool at the inventory of the container, and think the idea is noble.

Next time, use Molex

The trouble is, how idiot proof must I go ?  Should I then have a different connector on the mains supply to the psu, etc etc.

I want to avoid connectors as the equipment is going to the tropics, and I like to spray everything with clear laquer to waterproof it.

These guys that swapped the red and black over , wire up light boxes and high voltage neon lights, its a big signage company that connects up LED strips etc !!!

, but it doesn't matter because you can use a real terminal program.

OK I have installed the freeware Terminal.exe  which looks cool.

I have the SIM20 module connected to NewSoftSerial pins 14 and 15 on the arduino, so  I have removed the 328 chip from its socket, and bridged the RX and TX accross to the SIM20 Rx and Tx.  and linked the data/command pin to ground

I have set all the coms as per the SIM datasheet ( 9600,8,1, none ) and I think if I just send a CR/LF it should say OK, but I get nothing.

I tried sending a few query AT commands, but only the one light on the arduino board flickers, and no reponse.

Am I missing something obvious again ?
