Have you made any progress with this? I went in and changed the default deviceNames values but that just made new issues show up.

[bsdinis1]

you must use esp core 2.0.11 or esp core 2.0.10

[Cflyyyy]

you must use esp core 2.0.11 or esp core 2.0.10

Thanks so much!!! I thought I was going crazy.

2.0.11 seemed to worked better for me

[SalamunKawlam]

you must use esp core 2.0.11 or esp core 2.0.10

Thanks so much!!! I thought I was going crazy.

2.0.11 seemed to worked better for me

How did you get this version of esp core? I can only use the stable release (v2.0.14) or dev release (v3.0.0 alpha 3) from the additional board manager url.

Using version 2.0.11 actually worked! For people not knowing how to do this: you can select the version in the boards manager when installing esp32 by espressif:
