Hi,
One of my LILYGO® TTGO T-Beam was running 1.2.53.19c1f9f
and used with “–set is_router true” and worked fine for weeks.
Today I decided to solder the OLED and after switching the t-beam on it worked fine.
Then I upgraded the Firmware to firmware-tlora-v1-1.2.59.d81c1c0.bin and now the OLED
is not displaying anything. Like it is not powered at all.
A red led blinks once if i connect the usb port but the blue led is not flashing once a second
as usual.
First I throught I bricked the t-beam with the firmware-tlora-v1-1.2.59.d81c1c0.bin but then
i noticed that it still responds to “meshtastic --port /dev/ttyACM0 --info” etc.
I assumed that this could be related to “–set is_router true” so I set it to “–set is_router false”
but still no light in the OLED.
I downgraded to firmware-1.2.58.6af1822 and later even to firmware-1.2.52.b63802c
but still no OLED and no blue LED flashing.
I am wondering if this is a hardware problem, or some software setting causing this ?
Should I factory reset the device ?
Is there anything i cloud measure ?
Thanks in advance.
