Steinar,



I fixed the bug in AUTEX on this test version :

f6cte.free.fr/MULTICOM_TEST_10_09_2015.ZIP



Would it possible to test it with your serial transceiver?

Hi Patrick



Thanks for this new software.



I have been playing around with a module LoRa form DORJI a long time

(www.dorji.com/docs/data/DRF1278DM.pdf). It is using a Frequency

Spectrum protocol called "LoRa". With only a few mW I have been able to make

a 5 km long link. Until now I have only been using a simple terminal

application.



This evening I have tried to use MULTICOM instead of the usual terminal.

dl.dropboxusercontent.com/u/16381257/dorji.jpg



It is working perfect in ascii mode, but when I am trying AUTEX it is not

going so well .I am able to connect , but after a few sec the link is

disconnecting. I am not able to send any text.



I have tried to make a link without the dorji module. I have instead used

two virtual com ports on my PC connecting two instances MULTICOM together. I

am getting the same negative results.

Hi Patrick



I have been doing a new test today. This time I was using a band wide of

250K dl.dropboxusercontent.com/u/16381257/DORJI2.JPG . This made

a faster link and I was able to connect

Steinar,



RR for the transceiver. Have you tested through your virtual serial port? It

works here on mine.

Hello Steinar,



RR for all.

What band to you use before? However, I'm not sure to understand the

relationship between connection and bandwidth. Do you see one?



Could you exchange long texts (or files) without disconnection?

#20722 Sep 12, 2015

Hi Patrick



I was using a band wide of 125kHz in my first test. 125kHz gives a

264.2 ms in "time on air".

With my new 250kHz settings the time on the air is reduced to 132.1 ms.

All for a 10 byte payload packet.



I think I got some timing trouble when I was using a bandwidth of 125kHz.



Here is a "guide provides the basic information necessary for the

designer to evaluate the suitability of the LoRa modem for their radio

application. The design is split into two sections covering basic and

advanced design topics." ( quote from the "LoraDesignGuide" document) :

www.semtech.com/images/datasheet/LoraDesignGuide_STD.pdf



Here is more info about how to use LoRa modules:

Thanks for the information Steinar.

This XCVR seems very interesting (and cheap).

Hello Steinar,



I read the documents on the links. This serial XCVR seems a great choice.

However I have a doubt about the effective user bit rate which seems to me

much lower that the ones given.



Could it be possible to send in ASCII mode with MULTICOM the following

sequence (600 characters) with RF_factor =4096 and RF_BW equal to 125K and

then 250 K, and to note in how much time this sequence is transmitted.



IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII

IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII

IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII

IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII

IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII

IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII

IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII

IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIENDENDEND



TKS!



For information: I'm going to read these SX1276 data sheets:

Hi Patrick



Yes, this is a slow link, but is coming through ;)



With a RF factor of 4096:



35 sec with 128K

18 sec with 250k

Hello Steinar,



Thanks for this very interesting information, so the user bit rate is:

* for 125 K: 600*8/35= 137 bits/s (293 bits/s according to the DORJI

document),

* for 250 K: 600*8/18= 267 bits/s (586 bits/s according to the DORJI

document).



The DORJI document must refer to the rough bit rate.



Note for Bill: mea culpa, the DORJI receiver is a SdR even if the data is

exchanged serially.

There is no evidence of a bottleneck trend with the data shown, at

double the speed, transfer time is roughly the half.



Transfer time is always longer than what the rough calculation based on

raw signalling speed might indicate. There are overheads due to key up

and key down times, packet headers, wait times, and so.

Hello Jose,

>There is no evidence of a bottleneck trend with the data shown, at double

the speed, transfer time is roughly the half.

I agree, the problem here is that the bit rate in the DORJI data sheet is

ambiguous. The user can think to dispose really of 586 bit/s. Moreover, in

the case the LORA packet, it depends in fact on the type of coding, the data

payload, CRC or not CRC...

With the test done (600 characters) the bit rate obtained (293 bits/s) is

very favorable, as the payload is big so frames are built with the maximum

length of data payload.

Hi Patrick



First of all, this is min kind of radio hobby ;)



I have been doing some en testing with different types of "USB to com

dongles" and terminal programs. All give the same results.





By the way, I was able to break my own record a few day ago: 5.84km

dl.dropboxusercontent.com/u/16381257/avstand.jpg

I was using the MULTICOM setting up as a beacon at home, and my android

phone as a terminal in my car.

Hello Steinar,

>5.84km

It's an exceptional performance. Have you tried with very low output power,

let's say only 10 or 1 milliWatt?

(normally 3,16 (SQRT(10) times less range , for 10 times less power).



Did you experiment at 125 or 250 KHz?



73

Patrick
