Hi, I just want to push up this thread because I have another question. Bluetooth seems to be used fot telemetry but is there a possibility to use BT for teacher/student connection? I have a Jumper T16 where a BT module can be added to be used for this but is the X9D+ also BT capable for trainer/Stu...

Hi, I have done some OXS based flow meters with BMP280 pressure sensor for my friends towplanes. Now he is trying to adjust the correction factors. To give you an idea about the real flow rates he has done a series of tests with his two motors. Idle run was 10 minutes, full power 5 mins to get bette...

Hi, What about BT-Audio. I hate cable connections from transmitter to pilot so BT-Audio with BT-Headset would be nice. I could use a regular audio transmitter in the battery compartment but how can I disable the internal speaker without having a signal at the audio-transmitter. Is the audio signal a...

Hi, This might be right but for me a pitot tube is no option since it cannot be removed from the plane and is quite bulky with regard to transport of the model. I am using the WSTech TEK tube (Braunschweiger Rohr). This can be easily removed for transport and used on other planes as well. In my Vent...

Hi, In addition to OXS I am using the LinkVario Pro. In my opinion the best digital vario on the market. In my new glider I will test the airspeed sensing using the TEK-probe and a (I2C) diff pressure sensor who is connected to the TEK probe with a T-piece on one end and at the bottom of the fuselag...

Hi, Someone has created a library to handle the very sophisticated Jeti EX Bus. https://sourceforge.net/projects/jetiexbussensorcpplib/ The benefit of the EXBus is its speed and the fact that Servo positions are transmitted as well (similar to the Futaba SBus2). Maybe it is possible to implenet that...

Hi,
Thanks for this link but this is a Lua script working with OpenTX.
I am using Jeti so I cannot use this script.
But maybe these threads can be merged.

Hi, there are several values given, when a GPS is connected to the oXs but I am missing one which is standard on other sensors. This is the total travelled distance during the flight. Would be nice to have this implemented as an additional value. A filter to avoid large steps when the GPS reception ...

Thanks,

After this modification it works well.

Hi,

Just finished testing.
I used a pulse generator to generate 100 or 200Hz signals.
Input is port 8 according to the documentation.
In any configuration (just rpm, with GPS, with voltage/current) I get 1000rpm (Jeti protocol). even when no signal is present.

Hi again,

I have tested the signal coming from the YEP ESC and this is fine.
So there must be something wrong with the sensor. I will test this on the bread bord using a signal from a frequency generator.

Hi, I was testing another sensor yesterday and found a strange behaviour. This sensor is using GPS and dual MS5611 Vario and a ACS current sensor. When testing the sensor with my YEP 90 ESC (RPM output wire connected to port 8) I always get 1000 rpm even when the motor is stopped or at full speed. I...

Hi I am using an ACS758 with my sequencer project and found a little problem with the configuration. The files are attached. A0 is used for the current sensor, A1 measures the battery voltage using a 47k/10k voltage divider. When is set: #define NUMBEROFCELLS 0 I don't get a battery voltage paramete...

Hi, just a quick question. I have finished my sensor with GPS, 2 MS5611 (secondary with TEK connection), current sensor and RPM sensor. This sensor is in my Alpina 4001 which is used as a trainer model for our youth. I want to use the PPM-Signal to switch compensated vario and uncompensated. Am I ri...

Hi Marcel,

You can use PIN "PS" as this is the mode selector (high = I2C) and this is internally connected to 3V3 using a 2k2 resistor.
So just connect CSB with PS and it will use the secondary address.

Hi,

I was able to test your last version with flow sensor as well.
Now the pushbutton reset as well as PPM-Signal reset are working as well in combination with the BMP280.

Thanks for your quick help

Hi, It seems to work now but I can test more detailed tomorrow. ⸮rio Sensor:BMP280 I2C Addr=76 openXsensor starting.. milli=0 freeRam=805 vario setting up.. Vario Sensor:BMP280 milli=1000 calibration data #1 = 28048 error= 0 calibration data #2 = 25912 error= 0 calibration data #3 = 50 error= 0 cali...

Hi, I flashed the new code (with PPM Pin3) with this debug output (strippd since repeated ): ⸮rio Sensor:BMP280 I2C Addr=76 openXsensor starting.. milli=0 freeRam=801 vario setting up.. Vario Sensor:BMP280 milli=1000 calibration data #1 = 28048 error= 0 calibration data #2 = 25912 error= 0 calibrati...

This is the debug output. I just changed the PPM input to port 3. If you want I can also check with port 2- ⸮rio Sensor:BMP280 I2C Addr=76 openXsensor starting.. milli=0 freeRam=863 vario setting up.. Vario Sensor:BMP280 milli=1000 calibration data #1 = 28048 error= 0 calibration data #2 = 25912 err...

Hi, still the same problem with the new version: ⸮rio Sensor:BMP280 I2C Addr=76 openXsensor starting.. milli=0 freeRam=877 vario setting up.. Vario Sensor:BMP280 milli=1000 calibration data #1 = 28048 error= 0 calibration data #2 = 25912 error= 0 calibration data #3 = 50 error= 0 calibration data #4...

Hi, just the result (with the old version) using the MS5611 on the breadboard. It works. Seems to be BMP280 related. openXsensor starting.. milli=0 freeRam=901 vario setting up.. vario is up.. End of GPS setup Jeti Output Module: TX Pin=4 milli=4207 Jeti Output Module: Setup! Number of fields to sen...

Hi, This is the debug output I get with BMP280 activated: ⸮rio Sensor:BMP280 I2C Addr=76 openXsensor starting.. milli=0 freeRam=877 vario setting up.. Vario Sensor:BMP280 milli=1000 calibration data #1 = 28048 error= 0 calibration data #2 = 25912 error= 0 calibration data #3 = 50 error= 0 calibratio...

Hi, With my setup it makes no difference if debug is enabled or not. The sequencer works in both configurations. Only if I set the first baro to "BMP280" the sequencer is no longer working (with debug on or off). With "NO_BARO" it works well. On all these tests I was using a boar...

Thanks a lot for your efforts.

Hi all, Thanks Kalle for this advise. I am using a separate subfolder for every sensor configuration and one master directory with the code. I think it would be perfect (also for not that experienced users) to get the configurator tool back so different configs could be handled by the tool. But this...

Hi, I tried it with one board in the complete setup using the transmitter to generate the PPM pulses and with a raw board (without baro and GPS) by just using a servo tester to generate the PPm pulses. To make sure I try to use an older version with the same code. You are right. the pulse might be a...

Hi all,

I am having a serious problem with the sequencer.
Please check my config files (attached).
I am pretty sure that this code used to work before but now the sequencer is not working at all.
Of course I am using the latest OXS code.

Any ideas?

Best regards
Onki

Thanks so much for your help. Since the weather forecast for the weekend is quite bad I will find some time to give that a try. Another general question to all. How do you handle different OxS configurations (with/without GPS; with/without Flowsensor etc.) using the Arduino IDE? At the moment I put ...

Hi again, I did some testing on the modified code but I still could not reset the flow parameters. Neither using the PPM activated nor through the pushbutton reset. I tried id many times with different times but nothing happened. Same with PPM. I double checked the pulse lenght with my DC16 display....

Hi, many thanks for the info. Since the first sensor seems to be used for height measurement only I could use a less precise BMP280 as well as first sensor and use the MS5611 with tubing connection as second sensor? TEK Probe (Braunschweiger Düse) is already at the plane as I am using a LinkVario at...
