<0003> gsm322.c:257 Sync to ARFCN=104 rxlev=-65 (No sysinfo yet, ccch mode NONE)
Based on the low rxlevel, I guess it is not acquiring any meaningful signal?
-65 dBm is a pretty strong signal actually :)
It should be able to sync down to -105 dBm or so.
In [2], Steve said the internal antenna was switched off when the cable is plugged in, is it still true?
It's true and won't ever change ... it's a hardware switch, when you plug something in the antenna plug, it disconnects the built-in antenna.
| L1CTL_RESET_REQ: FULL!L1CTL_FBSB_REQ (arfcn=104, flags=0x7) | Starting FCCH RecognitionFB0 (1748:10): TOA=11712, Power=-106dBm, Angle=-22058Hz | FB0 (1775:11): TOA=12528, Power= -65dBm, Angle=-3818Hz | FB0 (1796:5): TOA= 5280, Power= -68dBm, Angle=-16117Hz | FB0 (1799:1): TOA= 96, Power=-109dBm, Angle= 7082Hz
It's weird that the power varies so much ... it's also weird that it even _tried_ to sync with a 22kHz frequency error .. It might try to sync to something that's not a C0 ...
Try to force the ARFCN to a known good cell (that you get from a phone with netmonitor) using the stick option.
