EN16 stuck with purple LEDs after flashing firmware 1.3.1 and 1.3.2

Flashing firmware 1.3.1 and 1.3.2 on my EN16, results in “Bootloader connection lost” message and device stuck with purple LEDs on (I am usually using page 1 with blue LEDs) right after flashing (device becomes completely unresponsive).

Both manual and automatic updates result in the same issue. Reverting to 1.2.39 solves the problem.

My PO16 is not experiencing the same issue (firmware 1.3.1 seems to be OK). Haven’t tried to flash 1.3.1 or 1.3.2 yet on my two PBF4 devices.

Grid Editor version: 1.5.5

Thanks for reporting this issue!

Are you using D51 or ESP based modules?

In this example E-32 means ESP32.

Can you export the configuration for the EN16 as a profile and share it with us for debugging?

Also it would be helpful if you could check whether the same issue happens if you clear the configuration before the update!

I hope we can resolve this issue soon!

If it is ESP32 based that please try manually updating to this firmware build: Release Grid v1.3.3 (2025-05-11-1441) · intechstudio/grid-fw · GitHub

Thanks for your reply.

My EN16, as well as my other devices (1x PO16, 2x PBF4), are all ESP32 based.

I tried to manually update my EN16 with firmware build 1.3.3 - before and after clearing each page configuration - but I am still facing the exact same issue in both cases.

Here is my configuration profile: grid-editor://?config-link=xeVrWP5DrNMK3uiS3pH7

Reverting back to firmware build 1.2.39 solves the problem.
