hi list,
I would like to run the c123(s) without the LI battery with direct
5V power supply only. Without battery the c123 display just blinks
and no PROMPT1 can be received.
Anyone knows a way how this might work ? (- like bypass or bridge
this 3 pin battery pins)
thanks for your help
(sorry for the lame add)

Try to add a capacitor between the + and -
Sometimes it works

Hi,

That won't work via the power plug ... (at least with osmocom, with the
default FW it may works if you have a big cap instead of the battery).
You can inject 3.7v directly at the battery pins with a big cap close to
the phone and that should work fine.
Check the C118 schematics to understand why.
Cheers,
Sylvain
