Re: HC-05'S Again

Hi Giovanni

Looks like I'm into the HC05

I had to update the pi and enable the hardware UART.
I disabled the serial console in the pi's config menu.

Do you know how long it's been since I did a loopback test... more old knowledge recovered and that checked out fine.

What was less obvious was selecting /ttyS0 instead of /ttyAMA0 to program the HC05, that discovery was kind of accidental but who cares now :>)

I did this:
*******************
AT+ORGL followed by CR and LF resets the module
the answer must be OK
AT+NAME=BLUEDUO followed by CR and LF sets the name to BLUEDUO
the answer must be OK
AT+PSWD=2357 followed by CR and LF sets the password to 2357 (if you do not do this the default password is 1234)
the answer must be OK
AT+UART=115200,0,0 followed by CR and LF sets the speed to 115200, stop bits to 1 and parity to none
the answer must be OK
****************

and got the correct OK answers, but was not able to communicate with the HC05 after that...


I now have to load BlUEDUO my android and plug the HCO5 into the DUO.

In retrospect I probably should have used a RS232 level converter and just done this on my linux box.


I will let you know how I do, thanks for the encouragement.

This is a very fasr test to see in there is a problem with the pi3 serial:
Please note that the s3 is a little bit different from the s2: the "good fast hw" serial is connected to bluetooth and the serial is a "poor man" sw one.
This sw UART is not capable to go as fast as 38400, so you be sure that you have switched the fase hw UART out of the BT.

The warranty is one year.
And while it does transfer to a new owner, the warranty is now expired.
The unit was purchased on August 7, 2016
I never had to use the warranty and the FDM-DUO is in Like New condition.
I think there's probably less than 20 working hours on it.....

Re: External 5V power supply for FDM-S2

Giovanni Franza
 

Hi Willi,
since S2 has a power led, you can see the led glowing when you connect the S2 to a powered USB HUB, so the power arrives from the power supply attached to the USB HUB.
I'me quite sure that, once powered from its supply, the HUB doesn't drain power from yout tablet, also you can attach mouse and keyboard to this HUB to further reduce power drain from tablet.
To be sure making mesaures there exists some USB digital power monitors available from Cina, but I haven't tested any of them.

Re: Debian linux 9

bill@...
 

I'm considering a Duo and haven't used wsjtx or fldigi.  Can you give a quick overview of what you have working?  Do you have waterfall, tuning, talking and listening working?  Can you encode/decode newer digital modes like olivia?  How about upgrade the firmware?

My main concern is the FDM-DUO is out, but I haven't been able to find much information about how to programmatically talk to the FDM-DUO.  Hell I've yet to find the warranty.  In any case a basic overview of what works with linux would be very useful.  Not everyone runs windows in their shack.


Re: FDM-DUO for sale - Price drop....

bill@...
 

I can't find any mention of the warranty.  Does elad offer one?  How long?  Does it transfer with a used sale?  How old is your unit?


Re: External 5V power supply for FDM-S2

You have probably ruled out switching power supplies already, which is a wise thing to do.

Possible sources:
1. Lithium battery power bank (usually marketed for charging cell phones). Will only last "so" many hours though. Here is my test of one.
2. "Amateur-grade" linear power supply, such as the Diamond GSV-3000 (possibly overkill in your setting, but still).
3. Lab-grade linear supplies, like those from Bel Power Solutions.

I've tried all of the above for various SDRs, and they all work. The Bel Power is surprisingly cheap, and I would recommend it. A discussion of ways to power your SDR (in this case the Perseus) is here
The S2 power consumption is only marginally higher than the Perseus.

There were linear (transformer-based) wall warts available in Europe some years ago, but I believe they are gone due to EU regulations.

Re: HC-05'S Again

Paul
 

Hello Giovanni

Thanks for the guide, and it's not tedious.
I am using cutecom on a Raspberry pi 3

Going back to basics I pulled out a old TTL pulse probe and checked the TX pin on the pi. I didn't see anything there... this could be due to the probe not being able to see the pulses on the pi output so I'm going to have to drag the scope out and look at the data stream. I have a Siglent 1202 and should be able to decode the serial stream as well as see the raw data pulses. While I am willing to do this I do start to wonder if it's worth the grief...

I have tried both 5V and 3.3v power as I have seen guides using both voltages. Neither one was successful. I do have FDM-S2 running on an notebook. I may just stay there for a while...


Re: External 5V power supply for FDM-S2

Willi Westrupp
 

Hi Giovanni,
when the powered USB hub is connected to the FDM-S2: does the FDM get power only from the USB HUB?
How can I check this?
I ask that because the USB power line from the tablet in this case is not interrupted. I have to try to reduce the power consumption on the tablet. Another possibility would be to branch off the two USB power cables on the socket and hang them on a longitudinally regulated power supply. Has anyone done that and did it work?

Hi Paul,
which program and which data speeed you used to program ?
If not already done I suggest to use 38400 bps to program the dongle.
In a previous message I posted a step-by-step guide (it could be tedious, sorry):
you can find here:
https://groups.io/g/EladSDR/message/12006?p=,,,20,0,0,0::Created,,hc05,20,2,0,5821789
Since yu do not receive response to AT commands I suggest to verify wiring and speed
(because 8N1-nohandshake-CRLF is ok, and led is flashing)
Hope this can be of help,

Re: HC-05'S Again

Fred Lodden <felodden@...>
 

Paul,
I had a similar experience trying to program up my HC-05. I twas very frustrating since following the instructions and the video to the letter did not produce any joy. I just could not get it into AT programming mode.
I even resorted to try programming it with an Arduino Uno and then I tried a Raspberry Pi.. There are articles on the web about how to do that. But even then following all the steps did not produce the result I wanted.
Then just by chance after days of messing around with all sorts of combinations of sequences and steps it worked! I was using the Arduino Uno at that stage.
There is a step where you need to hold the 5V line and the KEY line low and then bring the KEY line high and then after a delay bring the 5V line high, to get into AT mode. Well it was only after not following that step that I was able to get it into AT mode and I was able to program the device. I can't recall the exact sequence. I suggest you mess around with that sequence to see if something different gets you where you want to be.
After that I had a problem where the BlueDuo seemed to be only partially working but a post to Giovanni,revealled that there were a version mismatch between the Elad software and the BlueDuo version I had. A simple update fixed that.
Good luck

HC-05'S Again

Paul
 

I either have the worst luck buying HC-05's... The bluetooth dongle is the last little bit I wanted to get done for my go box, it was a workaround for the lack of band buttons.

I have tried four of them, from two different suppliers and cannot get a response from any of them. I have no problem getting into the programming mode, the 1 second period flash of the led, but cannot get it to acknowledge any AT command.
I am using 8,n,1 no flow control and end the command string with a CR/LF just like the video says

This should not be this difficult.

As I understand it there are some knock off BT adapters that are really HC-06's but I have no way of determining that. In retrospect, I would have been much happier if Elad had offered the dongles for sale or even better yet had incorporated BT into the DUO from the get go.

If anyone can point me to an alternative dongle I would appreciate it. I won't spend another dime on HC-05's
A $5 board against an $1100 radio, come on guys... why couldn't you just have included it

External 5V power supply for FDM-S2

walkabout creek
 

I would like to operate FDM-S2 on a tablet with external 5V power supply. For this I have to reduce the power consumption on the tablet. Is there a way to connect the FDM-S2 to an external 5V power supply? If so, what are the possibilities?

Right David! Now the registered Version "is somewhere" in a batch-file that sets up everything for ham-radio. Somehow 'fire-and-forget'.
fyi: I am using my FDM-DUO completely on remote. I am developping an front-end that can control the FDM-DUO in all aspects the SW2 does not have for all the set-up that normally must be done sitting in front of it...

Re: Serial port split

hi David!
you even can start it with a saved config without the key. always two extra clicks are needed. But surely it is always a question of fairness how long you 'test' a program before you pay your fee!
(I know what I am talking about. After some thousands of hour coding a programm some 500 OMs used it. Only one(!) payed a small amount)

So use it - and if it fits your needs - be fair!

Wolfgang is correct about VSPE.  However, if you do use it unregistered, I don't think you can automate starting it with a saved configuration.  With VSPE, you can save a configuration, then double-click the resulting .vspe file to start VSPE with that configuration already running.  That allows you to do things like start a VSPE session pre-configured at Windows startup, or save different configurations for different rigs, etc.  This feature is a timesaver for me (or, maybe I'm just lazy :).

Hello Tim,

FYI regarding the Elad amp and tuner setup. It may take a while, but in the meant time.  Take a look at my QRZ page KJ6YXI and you can see how I daisy chained my amps and tuner to get a QRP to put out 750 Watts. 

Good luck

Hello I am new to the group and just wanted to give some feedback. I am also new to SDR for the most part as I have played some with one of your competitors. I received my radio this week. It was very simple to setup and run in stand alone and not much tougher in SDR mode. I am very surprised with the receiver and I am very picky. I am comparing it to my Icom 7700! I have not even hit the surface with really learning all the function and features in SDR mode. Very impressed with a very small footprint radio! Please get the tuner/amp module done!
