XBUS - no data

[jasc76]

Hi

I tested with Spektrum DX9 and AR9030T and I get no telemetry values. FV shows baro but, I get no data. The reciever and stuff works, because with spektrum sensors, all works

[pierrotm777]

Thanks for your test. I just received my own Spektrum receiver an AR6610T. Do you have a picture of your connection ?

[pierrotm777]

When you type FVP or FVN in the serial console, do you see some change on your dx9 ?

[jasc76]

Sorry, didnt check the console. Just checked I have baro and its sending data

Picture, also no. But straight forward. like here: https://www.spektrumrc.com/ProdInfo/Files/SPM_Telemetry_Developers_Specs.pdf page 6 I know from MSRC, they use a transistor because they say the RP is not initializing fast enough.

[pierrotm777]

You say 'Just checked I have baro and its sending data' . You receive data from the RP ?

[pierrotm777]

Can you try this uf2 version and see if the altitude is returned ? oXs.zip

[jasc76]

You say 'Just checked I have baro and its sending data' . You receive data from the RP ?

No, I just checked with FV to see the RP sees data from baro

[jasc76]

Can you try this uf2 version and see if the altitude is returned ? oXs.zip

I will but will take until next weekend

I still fear its the same issue MSRC faced

[pierrotm777]

Did you have tried MSRC ?

[pierrotm777]

oXs2.zip Another version, sorry.

[jasc76]

Did you have tried MSRC ?

Yes, didnt work also. I did not mess with putting this transistor in. I put it aside and when you brought out this version I gave it another shot. Its not for me, a friend still flies Spektrum and I wanted to build it for him.

[jasc76]

oXs2.zip Another version, sorry.

I just did a dry test. This version is not working properly. He says GPS not detected but it worked with your other version. FV just doesnt output anything

GPS working with other version? Latitude and longitude was good values? Ok, it's a good news.

[pierrotm777]

FV return true telemetry values. Type FVP and FVN.

[jasc76]

GPS working with other version? Latitude and longitude was good values? Ok, it's a good news.

GPS was working in oXs but not over XBUS ! Also Baro not working over XBUS

[jasc76]

FV return true telemetry values. Type FVP and FVN.

Yes, and in your last test version https://github.com/pierrotm777/oXs-RP2040-i2c/issues/1#issuecomment-1722540158 FV doesnt return values.... In the first version FV worked

It was just an obersavation..... I thought FV should always work !?

[pierrotm777]

FV work always but return the good telemetry from oXs. FVP and FVN return always positives or negatives fixed values.

[jasc76]

yes, I know again, your latest test version from this thread is not working at all ! Fv is empty

Hello Pierre, I encountered a problem with the SRXL2 protocol at RCG and wanted to do some experiments with my old Spektrum TM1000 and DX8 via I2C/XBUS. But the XBUS-oXs-Version doesn't work. SDA0=TLM=GPio4, SCL0=PRI=GPio5 Do you have any idea what it could be? Best regards, Torsten

[pierrotm777]

Hello Satcomix, The XBUS version for oXs isn't ready and don't run for now. I am not a good programmer and don't find how to adapt the examples i have found.

[Satcomix]

Hello Pierre, I am not a good programmer too. :-)) I took a look at the srxl2.h/.cpp and srxl_sensors.h. I only found 5 sensors that transmit the telemetry data. Vario_Simple, GPS, Airspeed, ESC, RX_MAH I will ask Mstrens when we can do tests for the SRXL2 protocol again, as he is currently busy with the gyro system. If the SRXL2 runs properly, we will then build the XBUS together. greetings, Torsten

[pierrotm777]

SRXL2 is ran very well during my old tests. Xbus need an i2c input protocol. I have done some tests but I receive some bad info on my transmitter.

Hello Pierre, can you make one more test with the SRXL2 protocol and the latest version 2.10.8-test (and post it), as I cannot receive all sensor IDs on my old DX8. If you can receive all telemetry data, then the problem must be with AKob (Arnd). Greetings, Torsten

[pierrotm777]

Ok, I shall do a test tomorrow 😉

[Satcomix]

Ok, I shall do a test tomorrow 😉

Thank you very much for the test with SRXL2. I will ask Michel for the possibilty of XBUS telemetry for oXs_RP2040. :-)) greetings, Torsten

[pierrotm777]

Ok, this is the results of my SRXL2 tests. For theses tests, i use a TX16 MkII MultiProtocol DSMX Auto with the 2.10.8 version with the original uf2 firmware. I use EdgeTx 2.8.5, may be i should use 2.9.2. I have tried 2 receivers.

• SPM4648 (sattelite receiver).
• AR6610T. I had done my old first tests with a DX8 and the SPM4648 with success, if i remember, i used the 2.8.5 . But now, i receive only: TRSS 31 FdeA 7 FLss 0 Hold 0

With the AR6610T i receive more values: TRSS 31 FdeA 7 FLss 0 Hold 0 A2 5.06v Alt 0.4m Vspd 0m/s

No GPS

[pierrotm777]

Idem with 2.9.2.

Hello Pierre, Thank you for your test. Your result also agrees with mine and Arnd's. So I will reopen the older SRXL2 issue. Edit: I have reopened the issue. You are cordially invited to test it, four eyes see more than two. Thank you again and greetings, Torsten

[Satcomix]

Hello Pierre, Mstrens has released a new version 2.10.10-test, where there were changes regarding SRXL2. I now receive more data with my self-built version for the old DX8 Could you test this version again? If everything works now, I can close the issue again. greetings, Torsten

[pierrotm777]

I have already tried it with the same result. I have a new issue with all my gps ublox witch don't run. U-Blox center see this m8n. Curious.

You dont see the telemetry values,except the four values you hve seen before.??? I have Beitian BE-250 M10 Chipset at my oXs_RP2040 in GPS=U Mode. No Problems.

[pierrotm777]

Only these values and no gps with ALL protocols ! TRSS 31 FdeA 7 FLss 0 Hold 0 A2 5.06v Alt 0.4m Vspd 0m/s

I try to configure only my gps gps_rx=13 et gps_tx=12 but its not responding
