Hello,
I am getting false E7 water sensor alarms and wondered if anyone else had this issue?
The system will stay stable without out alarm for as long as I want until I start driving the motor. Could a voltage be getting induced in the sensor circuit? I have tried rerouting the sensor wires, but there is only so far I can move them in my setup.
Would anyone have any suggestions to fix? Should I try shielding the sensor wires? If so, where should I ground the shield to?
Yes, that’s what’s happening
The layout of your box is a bit unfortunate with the Rx so close to the motor wires…
You can try to twist the sensor wires together tightly and keep them as short as possible behind the Rx, don’t cross them with the motor wires
Hi Ludwig, thank you for the reply and the excellent BREmote project as a whole. I will give the twisted pair a try and then reconfigure the layout over the winter.
EDIT : I was missing the two dots in in the ?setConf command, solved 
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:
** BREmote V2 RX **

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!
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
