L96 3D_FIX pinout behavior

IoT Modules GNSS Module
1

Hello.
Coud you explain a behavior of 3D_FIX pinout?
Only I see in Hardware Design is “The 3D_FIX is assigned as a fix flag output. The pin will output a high voltage level to indicate successfull positioning.”
I’d like to use the pin to wake up main MCU.

Questions:

  1. What “fix flag output” does it mean (Fix Status of GSA or Valid/Invalid of RMC) ? in what output or PMTK-command/response
  2. Can pinout be programmed for 2D only or 3D only or 2D/3D fix?
  3. What PMTK commad described in Protocol Spec manages it?

Hi Ildar_Belkin,

  1. 3D_FIX pin output a high voltage level means GSA is 3D. Generally, module will output a 3D fix state when position available.
  2. There is a 2D fix state, but usually 2D fix last for very short time, even we can’t capture a 2D fix state. So the module will output 3D fix state finally. There is no need to program for 2D only or 3D only.
  3. I will send you L96 related documents via message.
