Got the same, can only connect to repeater right after flashing, after that USB Configuration cannot connect and console gives this error.

same here .. V1.14.0 with Heltec V3 3.2 and compiled Heltec_v3_sensor .. any solution ?

[LucLN]

Update :

my Heltec V3 board has 2 tiny pins on the back side without any labeling,
these are GPIO 17 & 18

connected a AHT10 sensor here
data is shown in Telemetry on Heltec_v3_companion_radio_ble
compiled Heltec_v3_sensor and data is there too

the log shows that the sensor is found .. but the mentioned error is still there:

Any Updates on this issue?
Still present in 1.14.1
Screen flashed for a second after flashing then nothing.

I have fixed it in my variant.
Let me push to MeshCore dev.

[IoTThinks]

I have pushed a PR for this.
#2452

You may use PowerSaving 15 to verify.
Tested and works perfect for 3 releases of our variant.

If it works for you, you can go to the PR to comment "Working" so it can be merged faster.
