LTE scanner buggy

Hardware MikroTik hardware general

I have a RB912UAG-5HPnD, with a Huawei ME909u-521 LTE module.

The board is running RouterOS 6.33, firmware 3.24.

It seems that the LTE scanning function is quite buggy.

  1. At times, it would not return any result after scanning for more than 10 minutes.
  2. And even if it returns results, it doesn’t always return the signal strength of all channels/carriers.
  3. Sometimes the LTE scanning cannot be started at all, with a cryptic error message:
    “Couldn’t continue - ERROR: 3 (6)”

It’s supposed to return the signal strength for all carriers, right? Otherwise it would be quite pointless, no?
