BREmote V2 - Open Source Remote

EDIT : I was missing the two dots in in the ?setConf command, solved :grinning:

Hey, I also wanted to remove the block time for steering, but I get decode errors and my config went back to default. Any thing I missed or doing wrong? (remote works and could configure the last time)


thanks in advance!

Hi Ludwig
I’ve ordered 2 remotes back in July and still haven’t received them? Is there still issues with customs or something? I have sent an email with no reply. Any news on deliveries to Australia?

Sorry to hear
Sales and shipping is @JasminRM topic
He will reply to you shortly. In the future please post questions regarding shipping and so on here:

Hi,
I completed tha assembly of the TX yesterday and it seems to work. But I can not get the RX to work. Out of the box it did not seem to have any firmware so I flashed it with the V2_Integration_Rx.ino.merged.bin image to address 0x0 and now it is booting. But it seems to be some kind of error when starting up the radio.
This is the serial output:

Starting Radio… Power: -9 Region: EU868 TOA: 0 Failed, code: -2

The bind led is flashing 3 times and the aux is off. I tried to hold the bind button to enter binding mode but is is not working.

Is my board faulty? How do I fix this?

Starting Radio… Power: -9 Region: EU868 TOA: 0 Failed, code: -2

Means there is an error initializing the radio module
Can you please check if there is a solder bridge around the main processor on the back of the Rx? Please also send HD images of both sides of soldering

Thanks for a very fast response!

hello ludwig i got a strange micro mouvement in the steering servo all the time and i think that it makes some bug in the direction when it come back to center is there a parameter i can modify

As you suggested it must have been a solder bridge between the pins. I took a knife and “cleaned” bethween all the pins of the radio chip on the backside and now it is working!

Looks like there was one here
Happy it works now!

Hey
Can you please check with another servo, this looks like your servo maybe has water inside
Also, how do you supply power to the servo and how do you supply power to the vesc? Do you have a schematic?

servo is supply by bec on the rx it was doing it first time never touch the water do the same in the water, when i turn the remote off it stop with power supply it looks like an order give by the remote, is the steering influence have to be a certain value ?

Hello Ludwig
I can’t get the configuration to display correctly on the terminal. The table displays for 1 second and then moves to another page, so I can’t read all the information.

Which BEC exactly? The BREmote BEC? That can’t be used for Servo, only for ESCs! For servo please get a high current BEC

You have a translator active in your browser? Please disable it!

yes indeed, thanks again, another little question can we have the return of the board battery on the TX if so how can we do it

bec servo is high power 4 amp sold as you said on the rx board

Please provide a schematic and image of the set-up

  • and - from the battery to the be, from the bec to the rx, - to gnd rx, and +from bec to the 5 volt rx and to the 5 volt servo make the bridge as you said, and gnd 5 volt and signal to the servo, esc cable in h
    is place
    the battery pin to check voltage come from the + that is connect for supply the bec

Thank you for the image
It looks correct, can you confirm if the output voltage of the BEC is stable and if the servo has not been damaged by any other reason?
Maybe try supply power with another 5V source instead of BEC and try another servo if you have one?
