Flipsky mini / bluetooth module wiring drama

[Joaquin Suavve]

Of course next to nothing "just plugs in" with the Flipsky products! I had a 7 pin female that would take the Bluetooth modules with the 6 pin male.

When in to the left... The wire mates to the red wire(3V), the green mates to the green(RX), the orange to the orange(TX).
And now my concern, the black wire lines up with the white line going into the module?!?!?

For those of you that may be struggling with the same issues...

Different controller, different use of the white wire, but the best interpretation I've found so far!

Flipsky Bluetooth Module 2.5G Wireless VESC NRF5.1 - ATBShop.co.uk

You can re-pin those connectors using a razor blade or spudging tool, gently lift the plastic tabs until the pin slides out:


Get one of these connector assortment boxes, select one that fits, slide the pins into the correct spots, win.

Thanks so much!
What is the specific name of those connectors and where can I buy one of those kit boxes?

A quick question...
Do the controller/ Bluetooth communication wires go: ⁰ TX to TX and RX to RX
or TX to RX & RX to TX???

I have not been able to get my phone to recognize the Bluetooth module/ controller.
The module and throttle share a ground wire and the throttle works fine.

Can you take a close up picture of the Flipsky plug? preferably with a millimeter ruler aligned on the pins so we can see the pin spacing.

There are are like half a dozen different JST connectors, I've worked with them enough we can probably get you sorted.

or TX to RX & RX to TX???

The traditional convention is TX>RX, RX>TX, but I've heard that Flipsky likes to buck that, and labels connections RX>RX, TX>TX.
The good news is you should be able to just swap TX and RX if you are not getting comms.

I have not been able to get my phone to recognize the Bluetooth module/ controller.

What kind of phone? What exact model of Bluetooth module?

This is what I have read/heard;
The nRF51822 uses BT protocol <=4.2, not compatible with Apple/iOS

The nRF52840 uses BT protocol >=5.0, compatible with Apple/iOS

I only have Android phones, so I can't test on Apple/iOS.

Thanks for your help A-Dam W!

My phone is a Galaxy 22+ Ultra

I will eventually get into the plugs but i've just have been splicing wires together, and now have a good way to do it.

After yesterday (with no communication), I swapped the connections to be TX>RX, RX>TX this morning and tried to connect my phone (with VESC tool) and it tried and I see the recognition code on the bottom of the screen for about 2 seconds connected BLE to C6,49,E3.49.E6.AE Then disappears and an error box reads:

READ FIRMWARE VERSION

Could not read firmware version. Make sure that the selected port really belongs to the VESC. If you are using UART, make sure that the port is enabled, connected correctly (rx to tx and tx to rx) and use the correct band rate.

This is making me more confused!!!! How do I enable a port on my phone?!?

Any help will be GREATLY appreciated!
