The "flowtoys connect" radio protocol has been significantly improved since it was first released in 2018, and as of firmware version 2.4 (released May 2020) it has been very reliable. The grouping procedure was also simplified and is now much easier, and very different from the original firmware. 


If you're experiencing radio issues, it could be due to these potential issues:

  • lights have different versions of firmware
  • lights are not grouped correctly
  • radio crashed
  • faulty radio
  • radio broke off the circuit board


1. Ensure all your lights have the same firmware


2. Ensure lights are grouped correctly

  • Click here for grouping instructions
  • Confirm they are NOT in a temporary/open group (go to P5M1: in current firmware, it should be white)


3. Radio might have crashed

  1. Do a power cycle/hard reset - Click here for soft reset/power cycle instructions
  2. Mark the light, if the same one crashes often, email us at support@flowtoys.com - we’ll replace it.


4. Faulty radio

  • It’s possible for a radio to be partially defective/work intermittently. Usually a bad radio can receive well, but not transmit well. You may notice a delay in other lights responding to it.  Mark the suspected light, and if you can confirm it is the faulty one, we’ll replace it.

5. Radio broke off the board

  • Open the capsule shell (see soft reset/power cycle video below) 

  • Check if the radio is breaking off the board or missing

    • If radio is breaking off the board or missing, please email us at support@flowtoys.com for replacement instructions.
