Andrew I updated the wiki

Andrew I updated the wiki page on the blue node with some sample output. I'll paste again here.
I flash this onto my arduno and reattached my bluetooth device to make sure I wasn't going mad.

[BlueNode.1] - RF disabled
SYNC> AT
OK
SYNC> AT+NAME=blueNode
OK
SYNC> AT+ROLE=1
OK
SYNC> AT+INIT
ERROR:(17)
SYNC> AT+INQM=0,5,15
OK
ASYNC> AT+INQ
OK
+INQ:12:37:E90912,520204,7FFF
device=12:37:E90912 type=520204 rssi=7FFF
OK

Another command you might want to try.

  // Set Connection mode.
  // 1 - connect the module to any address.
  sendBluetoothCommand("AT+CMODE=1", SYNC);

Put this before the AT+INIT and see if that helps any.

Thanks Brett for clarifying,

i've added the line

sendBluetoothCommand("AT", SYNC);
sendBluetoothCommand("AT+NAME=blueNode", SYNC);
// AT+ROLE=p1
// p1 - 0 Slave Role, 1 Master Role, 2 Slave-Loop role.
sendBluetoothCommand("AT+ROLE=1", SYNC);
sendBluetoothCommand("AT+CMODE=1", SYNC);
sendBluetoothCommand("AT+INIT", SYNC);
// AT+INQM=p1,p2,p3
// p1 - 0 inquire_mode_standad, 1 inquire_mode_rssi
// p2 - maximum number of bluetooth devices response
// p3 - the maximum of limited inquiring time. 1~48 (1.28s ~ 61.44s)
// 15*1.28 = 19sec
sendBluetoothCommand("AT+INQM=0,5,15", SYNC);

Same output alas...

Andrew that's a bummer. I don't know what could be wrong with your BT device its almost as if the antenna isn't connected!? You ordered from a different supplier this time?
You have set everything just like Gary and I have so all things being equal lets blame the hardware.

Sure is, as long as im not doing something stupid i dont mind blaming the hardware.

not much else i can think other than provide a 5v supply prehaps

original order was from the UK (more expensive but same week postage)

HC-05 issues

I have surrendered after fighting with 2 of these devices. Same response as you. Interestingly the second module I ordered was slightly different from the first, but behaved exactly the same.

Its got to be how its being

Its got to be how its being initialized but if everybody has the same unit how can this be so?
That make 3 units between Andrew and John that just don't function with my code, ok I missed out the AT+INIT and when I retested my code I got error(16) "SSP not initalized" but onced Iadded AT+INIT got error(17) "already initialized" and the unit worked, as per my wiki page.

I find that hard to believe the defect rate is this high. Maybe I should buy another and hope I get a dud so I can investigate. This is surreal. Gary are you using my code or some other variant? What is your AT sequence?
Yours work right?

Brett,

I haven't tried your version of the code yet sorry, stupid iphone and then the raspberry pi stuff put it on a back burner.

i can try to give it a go and see if it works with my unit.

I had success with my original attempt though, init code shown below:

  BTSerial.begin(9600); delay(200);
  BTSerial.write("AT+ROLE=1\r\n");
  delay(500);
  BTSerial.write("AT+INQM=0,5,15\r\n");
  delay(500);
  BTSerial.write("AT+RESET\r\n");
  delay(500);
  BTSerial.begin(38400);
  delay(200);
  BTSerial.write("AT+INIT\r\n");

I did this as I was concerned the key pin wouldn't go high straight away and the datasheet suggested this might cause a connection at 9600 baud. Therefore I opted to do this, reset then switch to 38400 for the scan.

The fact that Andrew is getting OK responses though suggest your code has the correct baud rate so I can't see what is different.

Best I check your code after a factory reset of the module maybe

HC-05 command mode

Andrew

Have you noticed that the module starts to flash fast ie it drops out of command mode. I have tried every combination of commands, including delays between them, on 2 modules. I give up! On to the next project.

hc-05 variants

I don't know if it helps at all but on the hc-05 adapter board that came with mine there is a tiny switch that has to be continually pressed to keep it in AT mode. Otherwise it tries to open a transparent Bluetooth serial data link. Part of the problem with progressing my nodes further

Thanks for the info,

I need to check the FTDI levels for the new board, the new adaptor board suggests the comms needs to be at 3.3v

its also possible it requires a 5v + supply and not 3v

no switch as far as i can see....

Hi Andrew.

Mine is the as same as the one on the left. I connected both 3.3 and 5v but not sure if I needed to.

It worked fine. Still waiting on a new ftdi comms cable before I can flash Brett's script and have another play.

Thanks Garry,

Regarding the supply V+, i've not read the specification fully but Brett does mention 3.3V was sufficient, this may however be for the type of adapter board variant he is using, something i need to check to rule out supply issues.

my old module gave me nice OK Acks, it just didnt detect any devices so i suspect its faulty as theres not much we have not tested.

The new module doesnt even go as far as to respond, tried various comm rates but from my understanding once in AT mode it will communicate at 38400 which is what Bretts sketch is setup for, prehaps i need to concentrate in getting this adaptor board / hc-05 module into AT mode, the config could be different

This is the second variant - http://www.ebay.co.uk/itm/201005161594?ssPageName=STRK:MEWNX:IT&_trksid=...

Andrew,

if you email me your address I will post you mine to try out.

I cannot use as I intended due to iphone bluetooth probs so whilst I'd like to return to this project at some point I'm not in any rush at the moment.

at least you can test one that we now is working.

Hoping to pull a list of connected devices from my router next to do something similar with wifi. Not holding my breath though!

Interesting idea for the pi

Interesting idea Mark for the pi and beaglebone installs.

a lua script using io.popen to run arp-scan and capture the response. Then it just parsing and endpoint generation?!

sure it's more difficult than that but I'm sure it's doable.

thats another weekend accounted for :)

Arp scan

I've been using arp scan with my Raspi, it seems to work OK with my wife's 4S but is not really reliable with my 3GS.

This is the line from my python script:

ping4s = Popen("arp-scan 192.168.0.5-192.168.0.10 | grep xx:xx:xx:xx:73:44; echo command returned $?",shell=True, stdout=PIPE).stdout

If I scan a subnet that goes

If I scan a subnet that goes via an L3 router that bridge network segments inside my ESX box, every VM inside comes back with the same MAC address. The L3 router is correctly subtituting its MAC so it can relay traffic. For a flat network space this will work but beware if you are routing traffic over several IP spaces (like I do).

brett@beaglebone:~$ sudo arp-scan 192.168.4.0/24
Interface: eth0, datalink type: EN10MB (Ethernet)
Starting arp-scan 1.8.1 with 256 hosts (http://www.nta-monitor.com/tools/arp-scan/)

192.168.4.225   00:0c:29:3d:c7:c6       VMware, Inc.

OR

Given you know the target MAC you can also use arpping - 0 means it there 1 is a failure.

brett@beaglebone:~$ sudo arping -c1 -ieth0 -q 00:14:bf:8e:7e:e4; echo $?
0
brett@beaglebone:~$ sudo arping -c1 -ieth0 -q 00:14:bf:8e:7e:e9; echo $?
1

Given this is already the exit code it makes it easier to call, you don't need a popen. In LUA its a one liner.

retval = os.execute("arping -c 1 -i eth0 -q 00:14:bf:8e:7e:e4")

Setup a timer to do this say one a minute and update a BSC endpoint STATE to be on/off etc...
Oh and "arping" is already on your livebox too !

Hi guys

So glad it worked for you Andrew, but now I need you guys' help. I am now on my third HC-05 module and they all start flashing as soon as I give them the INQ command. Have any of oyu found a way to solve it? If not, do you have a link, make or model to one I can try and purchase that might work for me?

It should probably be noted, that I am doing Arduino for my project.

I have a Stack Overflow question about it as well: http://stackoverflow.com/questions/23221336/hc-05-bluetooth-rssi-not-wor...

I really wish i could advise you on how to get it working but as discussed above it seems we are missing something between different comms boards or the QC on these modules is terrible and a shed load do not work at all.

The module Garry supplied me with is identical to my original module (i.e same comms board) and worked 1st time, my original modules appear to have behaved as yours did.

maybe 4th time lucky?
