Firmware 4.5.0 has gaps at high speeds (Approx. >65mph) #238

Closed Masaya-RT closed 5 months ago

Masaya-RT commented 5 months ago

CTP Users are reporting spotty coverage at high speeds. Description: Mapping is consistent, but very thin. Dots become spread out like morse code.

Steps to Repro:

  1. Drive under 55 mph for a few kms
  2. Switch to higher than 55 mph for a few kms
  3. Switch back to under 55mph for a few kms
  4. Download FrameKms to phone
  5. Observe FrameKm data in App

4.5.6 looking pretty good so far. Some drift in Masaya and a tester's drive DB files aren't increasing, but also aren't being purged.

Alexei pretty confident, but will look around for a little
