Wireless Bridge Mission Planner connection help.

[ArtimisFowl888]

I am trying to use the M5Stamp C3U Mate connected to an R9M for the wireless bridge mode. When I try to connect to the autopilot in mission planner, I get stuck at the Mavlink connecting... dialogue.

Is there a param or mLRS setting that I missed? I can get telemetry on the Yaapu script.

[ArtimisFowl888]

I rebooted my computer and am no longer able to replicate the Mavlink connecting... dialogue. Instead, I just get connection failed.

Can you share the Arduino sketch you uploaded to the C3U Mate? Did you uncomment the board define?

Here is the sketch I am using.

I did uncomment the define

A few thoughts:

• The attached has no versions uncommented, 'MODULE_M5STAMP_C3U_MATE_FOR_FRSKY_R9M' is the one you want because it accounts for the R9M inverted serial
• The baud rate on the Tx module (can be set via Lua) should be 115200, this is the default so not sure if you've changed

Yes, sorry I just relized the to .ino file was set to read only for some reason and my edits had not been saved. I have unlocked the file and reuploaded the sketch to the M5STAMP. I am still getting the same error.

I have not changed any baud rates other than the RX and the Serial1_baud to 38400.

@brad112358 Do you have any thoughts here? Figured that using the C3U Mate should be pretty straightforward.

@ArtimisFowl888 we will not kick you out here but pl consider the next time to use one of the discussion&support channels, i.e. the discord channel or the rcgroups thread. The github issues are generally NOT the place for support and trouble shooting. THX.

on your matter, can you pl post a picture of a setup

[ArtimisFowl888]

MY apologies I will use the Discord next time.

I have a R9MM connected to a MATEK F405-WING-V2 on UART1 and SBUS in pin. For the TX I am using a R9M with the M5Stamp C3U.

many thx. the intresting bit cannot be seen, namely how the wiring from the esp32 to the r9M board looks like :). The ESP32 does hve the labeling "C3U" on the bottom side.

@ArtimisFowl888 Doesn't dip switch 1 need to be up for Serial? From the Docs:

[olliw42]

good catch!

[brad112358]

Yes, also what is the led on the esp32 module doing?

That was the issue it is connected to mission planner now. I remember reading it when I first set it up, I must have missed it when trouble shooting.

Thank you, for all the help and keep up the great work.

Good to hear - I will close this issue then as all is working.

[olliw42]

great! glad to hear it's working all fine now for you
