Using LittleBee 20A OPTO Pro ESC ESC wired to the PDB Signal and ground wire from ESC to FC When connected the battery, there's 3 beep/tone instead of 5. When connected to BLheli suite, when I clicked check, all ESC are blank. I tried to click Read Setup, it will prompt me "Connection to ESC#1 Failed!" Solved! Turns out that I soldered the ESC signal wires to 5V. • Posts: 1,773 Threads: 30 Likes Received: 1,199 in 755 posts Likes Given: 714 Joined: Oct 2016 Reputation: 45 I think I recall that only 3 beeps is an error sequence for incorrect endpoint settings. But I could be wrong.....Have you calibrated them? • Posts: 2,416 Threads: 51 Likes Received: 1,861 in 1,175 posts Likes Given: 3,315 Joined: Mar 2016 Reputation: 74 Have you tried BLHeli configurator (Chrome app) instead of BLHeli Suite? • Posts: 947 Threads: 66 Likes Received: 350 in 248 posts Likes Given: 164 Joined: Apr 2016 Reputation: 34 Sounds like the ESC is not reacting to the commands from the FC. What ESC pwm protocol are you using? Try oneshot or multishot • Posts: 16 Threads: 2 Likes Received: 5 in 2 posts Likes Given: 0 Joined: Jun 2017 Reputation: 0 (17-Jul-2017, 06:52 PM)RENOV8R Wrote: I think I recall that only 3 beeps is an error sequence for incorrect endpoint settings.

Try oneshot or multishot Absolutely no idea, just done with all the wiring and trying to follow video guides on youtube but stuck at the "check" stage. • Posts: 12,099 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 The error you have reading is when you do not connect your battery when you are trying to read your ESCs. • Posts: 16 Threads: 2 Likes Received: 5 in 2 posts Likes Given: 0 Joined: Jun 2017 Reputation: 0 (17-Jul-2017, 07:24 PM)sloscotty Wrote: Have you tried BLHeli configurator (Chrome app) instead of BLHeli Suite?

So you are saying I should or should not plug in battery when reading the ESC? • Posts: 12,099 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 You have to power the esc with battery.

What I did is plug in USB, connect to BLheli Suite, plug in battery, hear 3 tone, click "Check", blank result. • Posts: 2,416 Threads: 51 Likes Received: 1,861 in 1,175 posts Likes Given: 3,315 Joined: Mar 2016 Reputation: 74 Just in case it's possible, you can't have Betaflight "connected" at the same time. • Posts: 16 Threads: 2 Likes Received: 5 in 2 posts Likes Given: 0 Joined: Jun 2017 Reputation: 0 (18-Jul-2017, 11:49 AM)sloscotty Wrote: Just in case it's possible, you can't have Betaflight "connected" at the same time. Yup, understand this point. Was able to connect to BLheli Suite but just can't detect the ESC. • Posts: 12,099 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 (18-Jul-2017, 09:46 AM)godzilla Wrote: What I did is plug in USB, connect to BLheli Suite, plug in battery, hear 3 tone, click "Check", blank result. Did you select the correct Com port? • Posts: 2,416 Threads: 51 Likes Received: 1,861 in 1,175 posts Likes Given: 3,315 Joined: Mar 2016 Reputation: 74 There were issues with passthrough on "some" (not all) FCs with Betaflight 3.1.6 and 3.1.7. For F1 boards installing 2.9.1 worked for flashing/configuring. For F3 boards some reported rolling back to 3.1.5. You might give that a try (depending on your FC). You can always go back and upgrade after you are done flashing/configuring your ESCs.

Technically, you have not connected. If you did, the screen would turn pink. • |
