I only have the board for one more day. And no time left for more test rides. The problem only came when my body was between remote and receiver. Dude rides with remote in his back hand so should be minimal disruption. He is aware of the issue.
If I can’t find any easy solution tomorrow, he is just gonna have to monitor the situation and report back.
I meant the software, I get that they’re different hardware, but it’s the same manufacturer. So, I’d be surprised if the procedure to set the failsafe is any different. Worth a try.
I’ve ordered one of these Maytech V2 remotes. I noticed in the manual they recommend using throttle over PPM/PWM and to not use VESC throttle. I could not think of any other reason as it having something to do with connection stability. Have you hooked it up via UART, PWM or both?
I’m not looking forward to dropping connections, had my share of that.
EDIT: actually having a good look at the pictures is a good idea before asking. PWM only I see.
Only ever tried ppm as that’s what I’m used to being honest. I saw the uart called out in the manual but didn’t take it as a reco. Maybe the changed the wording after they had more real world data? What does it say in yours?
I’ve written Agnes an Email asking to clarify the recommendation. I thought of it as unconventional but I figured they must have a reason to recommend these settings. Maybe im missing something, anyone care to share their 50 cents?
I had it set up in ppm and didn’t hook up the necessary wires to get speed telemetry data. So I did have it set up the reco’d way? Unless I’m not getting something that’s not the clearest instruction. Ppm for throttle but uart for telemetry info? Don’t you have to pick one or the other?
The manual recommends PPM for throttle, UART for data. That’s what’s weird because why would you make an extra PPM connection when you have UART already available as well for the throttle signal?
Would you then power the receiver over UART and connect the PWM throttle signal only or power via the PWM connection and connect RXD/TXD for UART only?
I don’t see the logic in this. My logic would be:
Receiver/ESC does not support UART or you don’t want to use UART -> connect PWM.
Receiver and ESC supports UART, connect UART only.
For the V1, you needed to separately wire battery leads to the remote receiver to get battery voltage reading on the remote screen.
I’m assuming the V2 works the same way. You just hook the uart to the remote receiver so it can transmit the telemetry data to your screen instead of battery.
Same with the V2. We measured the signal strength to see why this is happening and saw, that the dB is the lowest we’ve ever measured. It’s enough to put the remote in your pocket to completely loose loose the signal. If you were on the throttle the board keeps going for 1-2 sec. If you are in a city where are many signals everywhere, you can also loose the connection.
Another thing is, that you don’t get the UART data for newer VESC FW versions.
For those reasons we think, that we will go with FS VX2 Pro in the future.
Yep this is why went back to a nano for all my boards. Being able to use one remote for all of them is nice too. I’m still so mad at this maytech remote, it should be the best option on the market RN but the signal issues make it a non-viable solution for me as I do 99.9% of my riding in city areas.
The standard antennas on the Maytech are like 0dB. With zero Chinese dB on top. I have used similar antennas in routers/FrSky receivers and there does seem to be a small quality difference in those antennas.
@Chricious Have you tried with an antenna like on the Metr Pro? That could increase signal strength. I’m gonna swap the Maytech antenna for one like that and try some bigger rod antennas as well. I should be able to get out with an RF explorer next week to see if there’s a major improvement in signal strength/quality.
I haven’t as I understood the issue to be more due to what the signal algo does when its overloaded with signals. Not as much the strength. I am not a remote wiz or anything like that though so the two might be related. dunno.
Def interested in your experimenting though. Please continue to post findings. If I can make this remote work in some kind of constantly safe way I’d be all about it.
The question was directed to @Chricious since he has already measured the signal strength
I will post my findings! I just really want to use an Evolve-style remote, I seriously dislike controlling throttle and brake with my thumb or with only one finger. I hated the old Evolve GT remote.
That’s a good idea. Unfortunately we can’t use such an antenna for a production series board for design reasons. But may be it would help to just swap the antenna with a higher quality built in antenna. It should be worth a try, even if I don’t think that it will help a lot.
