Inav 2.0.1 when Bluetooth is connected to EZ GUI and when transmitter is on no signal is received #4151

Closed RichardAnkur closed 5 years ago

RichardAnkur commented 5 years ago

Hello I have the omnibus f4 pro v2 flight controller board (black one) which I had ordered from https://robu.in/product/omnibus-f4-v2-pro-flight-controller/ I have connected my ublox neo m8n GPS and compass on UART 6 and UART 3 and I am using a flysky fs i6x transmitter and fs iA6B receiver which is connected to sbus/ppm pin using ppm.The firmware which I had uploaded is the omnibus f4pro...and not that ledstrip one. And now I have connected my HC06 Bluetooth module to UART 1. The problem is that when I plug in the battery and connect the bluetooth with EZ GUI app it works perfectly but as soon as I turn on my transmitter.....the female voice from EZ GUI tells data not received. Suggest me a solution

what do you have active for that port? I had a similar issue with mobileflight thinking i had to have mavlink and msp on the same port. when the aircraft was armed the msp stopped and mavlink took over.

this was incorrect and i just needed msp on that port.

At UART 1 i had connected my Bluetooth module and msp is activated on that port with a baud rate of 11260. When the transmitter is off it EZ GUI APP works fine....I can upload the waypoint but as soon I I turn on my transmitter the connection with Bluetooth is lost and I am unable to see the live status of waypoint .... how the quad is crossing the way points and completing the mission. The receiver is connected to the sbus/ppm which is j7 on omnibus f4 v2 pro (black color board).

i would suggest trying a different uart it sounds like uart 1 is also the one used for PPM maybe? I use sbus & crsf so not sure which port the ppm input is on

RichardAnkur commented 5 years ago

My UART 6 and UART 3 is reserved for GPS. Only UART 1 is free

wx4cb commented 5 years ago

have you tried soft serial?

RichardAnkur commented 5 years ago

Means you are telling me to use the two pins RX and tx above moto_vcc ....... Connect RX from Bluetooth to tx in fc and tx from Bluetooth to RX in fc......and then I will get a additional option below uart6 named softserial....

wx4cb commented 5 years ago

not sure which pins they are on that board, but it's either that or you unsolder the gps temporarily to try that uart. it sounds a lot like that ppm and uart 1 pins are on the same port. but not having that board, i'm clutching at straws

If you want to use UART1 on the Omnibus F4 PRO v2 for something else than S.Bus you need to use PPM for the receiver and remove the S.Bus jumper.

The solution by @shellixyz is a correct one, it is even mentioned in the docs: https://github.com/iNavFlight/inav/blob/master/docs/Board%20-%20Omnibus%20F4.md

Closing, thanks guys

Yes @shellixyz is correct but now I have connected my Bluetooth to the softserial pad and receiver to UART 1 and it working perfectly. Thank you for helping me out
