Micro maestro = mini maestro ? problem with "Papywizard"

I want to know…Is there any difference between Micro Maestro and Mini Maestro ?? ( I mean at the “coding level”)
I had a problem with connectivity between Pololu Mini Maestro and Papywizard http://www.papywizard.org/(a free panohead control software, Papywizard is entirely written in python)
for more details…if you do not mind, please visit this forum : http://www.kolor.com/forum/t13713-papywizard-panoduino-can-t-read-position-and-failed-shoot-session

Thanks for your attention…

I just want to add info to make it more clear:
In the forum, appears anomaly, where the use Pololu Micro Maestro Usb and Pololu Mini Maestro Usb (both use a bluetooth module and papywizard as wireless control) produce different effects:

Papywizard (bluetooth driver) <—> wireless connection <—> Bluesmirf Gold BT + Pololu Micro Maestro Usb = success shot session http://www.kolor.com/forum/t8574-new-papypololu-head-in-the-works

on the other hand …

Papywizard (bluetooth driver) <—> wireless connection <—> Bluegiga WT-11 BT + Pololu Mini Maestro Usb = failed shot session http://www.kolor.com/forum/viewtopic.php?id=13713&p=2
Papywizard (bluetooth driver) <—> wireless connection <—> DFRobot BT V3 + Pololu Mini Maestro Usb = failed shot session http://www.kolor.com/forum/viewtopic.php?id=13713&p=1

Is the problem on Micro Maestro Usb vs Mini Maestro Usb … or at Bluegiga WT-11 BT/DFRobot BT V3 vs BlueSmirf Gold BT ??

Thanks…

Hello, thelight.

Did you use the Maestro Control Center to make sure your Mini Maestro and Micro Maestro have the same serial settings? What are those settings?

–David

Yes I use Maestro Control Center…and channel setting and serial setting are very similar for both of them (Micro Maestro and Mini Maestro)

Micro Maestro channel setting and serial setting (success) = using bluesmirf BT :

Mini Maestro channel setting and serial setting (failed) - it’s mine - = using Bluegiga WT-11 BT and DFRobot BT V3 :
here the screenshot = http://www.kolor.com/forum/viewtopic.php?id=13713&p=1

then what is wrong?? because both use the same software (Papywizard)

Since the Maestros have the same, correct, serial settings, it sounds like there might be something wrong with one of your bluetooth connections. You should try to debug it. For example you could take the Maestro out of the system, connect RX and TX, and just do a loopback test using a terminal program (if that’s the type of USB interface you are using). You could try swapping the bluetooth interfaces but not swapping the Maestros and see which setup has a problem after performing the swap. Separately, you can test the Mini Maestro’s TX and RX lines directly using a USB-to-serial adapter.

Thanks for the answer…
I want to add some basic information…Papywizard is running on 3 operating system…(PC windows, maemo (nokia N700, N800,N810 and mac os) and for connection, Papywizard use wired and wireless. In my case, i’m using wireless connection (both in windows version and maemo version -Nokia N810-). For controlling Pololu Mini Maestro, I use “Panoduino plugin” and Papywizard give 2 choices for wireless connection —> “Serial Driver” and “Bluetooth Driver”. Based on my experiment, I only fail when using the “Bluetooth Driver” and successfully when using the “Serial Driver”. On the other hand, there are reports that the use of Micro Maestro and Bluesmirf BT are successful, both in serial driver and bluetooth driver, here for the detail (my case) :

Papywizard on PC (Panoduino : serial driver) ----> USB Bluetooth Dongle ----> (((( <- wireless connection -> )))) <---- DFrobot BT/Bluegiga WT 11 <— Pololu Mini Maestro = SUCCEED

Papywizard on PC (Panoduino : bluetooth driver) ----> USB Bluetooth Dongle ----> (((( <- wireless connection -> )))) <---- DFrobot BT/Bluegiga WT 11 <— Pololu Mini Maestro = FAILED

here Papywizard on N810 :

Papywizard on N810 (Panoduino : bluetooth driver) ----> (((( <- wireless connection -> )))) <---- DFrobot BT/Bluegiga WT 11 <— Pololu Mini Maestro = FAILED

Papywizard on N810 (Panoduino : serial driver) ----> = FAILED —> connection is FAILED because there is no serial python module available on maemo OS

Thanks for the detailed information. The first result you reported indicates to me that the Mini Maestro and the bluetooth hardware it is connected to are functioning. Unfortunately I don’t know why your other options are failing, but it seems like it’s probably a driver problem.

–David

I think the problem is not the “driver”, but the hardware itself (maybe on bluetooth module OR mini maestro --it’s just my opinion :smiley: )…here my explanation…
Info : all “combinations” below using papywizard + bluetooth dongle on PC windows and “Panoduino Plugin” is selected/active :

  1. The combination : Bluesmirf Gold BT Module + MICRO Maestro (6 channel) = shoot session reported successfully by Frédéric (the maker and developer of Papywizard software) - both on “bluetooth driver” and “serial driver”…here the link http://www.kolor.com/forum/t8574-new-papypololu-head-in-the-works

on the other hand…

  1. The combination : DFRobot BT Module V3 + MINI Maestro (12 channel) = Failed…the failed condition only happen on “bluetooth driver” but succeed on “serial driver”
  2. The combination : Bluegiga WT11 + MINI Maestro (12 channel) = Failed…the failed condition only happen on “bluetooth driver” but succeed on “serial driver”

After conducting an investigation on the bluetooth modules, I had found the facts that : Bluesmirf Gold BT Module, DFRobot BT Module V3, and Bluegiga WT11 BT Module…has similarities ----> all are 3.3 volt devices :

a). Bluesmirf Gold BT Module http://www.sparkfun.com/products/10268 is 3.3 volts level device, that use “RN-41 BT module” as core http://www.robotshop.com/PDF/RN-41.pdf…Bluesmirf BT Module unit can be powered from 3.3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant…because using internal “Level Shifter”…as in schematic http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Wireless/Bluetooth/BlueSMiRF-ChipAnt-v15.pdf
b). DFRobot BT Module V3 http://www.dfrobot.com/index.php?route=product/product&path=45_79&product_id=360 was also 3.3 volt level device, that use “CuteDigi BMX Bluetooth” as core http://www.dfrobot.com/image/data/TEL0026/TEL0026_Datasheet.pdf…DFRobot BT Module V3 unit can be powered from 3.5V up to 8V because using internal “Level Shifter” too…
c). I realize that Bluegiga WT-11 http://www.bluegiga.com/WT11_Class_1_Bluetooth_Module was also 3.3 volt device http://www.bluegiga.com/files/bluegiga/Pub%20files/WT11i_Product_Brief_140711_lores.pdf and Mini Maestro is 5 volt device … then I use external “Level Shifter” or “Level Converter” ; product name is DT-I/O Level Converter (DT-I/O Level Converter modifier module is a digital i/o voltage 5V to 3,3V and vice versa. This module can be used to connect the i/o 5V digital devices to the i/o digital device 3,3V) http://innovativeelectronics.com/innovative_electronics/pro_dtio_Level_Converter.htm

Unfortunately…I don’t have Bluesmirf Gold BT Module and MICRO Maestro…so I can’t make comparison (combination Bluesmirf Gold BT + MINI Maestro…and…combination Bluegiga WT11/DFRobot BT V3 + MICRO Maestro…) and make conclusion about this problem…
:smiley: Maybe…someone on this forum (if don’t mine and had a hardwares) :smiley: could help to conduct “combination” experiments and report the results here
— Info : all “combinations” below using papywizard + bluetooth dongle on PC windows and “Panoduino Plugin” is selected/active —
here Papywizard v2.1.21 win32 : http://www.adrive.com/public/62997348e3c495b1a8f1820b263fb96941ef8ac10a01b201bc9078c41a95e533.html (don’t know why…today, papywizard site can’t be opened…so I reupload it) and the “combinations” are :

  1. The combination : Bluesmirf Gold BT + MINI Maestro (12/18/24 channel) :
    “bluetooth driver” = succeed or failed ??
    “serial driver” = succeed or failed ??
  2. The combination : Bluegiga WT11 BT + MICRO Maestro (6 channel) :
    “bluetooth driver” = succeed or failed ??
    “serial driver” = succeed or failed ??
  3. The combination : DFRobot BT V3 + MICRO Maestro (6 channel) :
    “bluetooth driver” = succeed or failed ??
    “serial driver” = succeed or failed ??

Thanks… :smiley: :smiley:

I’m sorry…download link on previous post was broken…so I just want to update papywizard (win 32) download link to anyone who want to make experiment with it :smiley:

win 32 & 64 bit : http://download.gbiloba.org/papywizard/win32/Papywizard_2.1.21-1_Install.exe

and for another OS (linux, maemo (n810, n800), and mac os) can be download in this webpage : http://www.papymerlin.com/t%C3%A9lechargement-papywizard/

and I think, (based on previous post)…you don’t need to try with all (3) combination, it’s only need (1) combination to make conclusion about “papywizard problem” :

The combination : Bluesmirf Gold BT + MINI Maestro ( only on 12 channel version) :
“bluetooth driver” = succeed or failed ??
“serial driver” = succeed or failed ??

Thanks for your help…
