Image not changing visually even if Gain is changed and read correctly from probe

[chr-wei]

Describe the bug
The output image does not change visually when changing Gain [0.0 ... 100.0], but the Gain is correctly set to the probe (setParam / getParam sets and retrieves correct values).

Setting ImageDepth changes depth correctly (in principle something works)

To Reproduce
Steps to reproduce the behavior:

1. Run Solum API with solum.setNewProcessedImageCallback(...)
2. Set gain solum.setParam(Gain, value: gain)

Environment:

• SDK variant Solum, Swift Framework (macOS, iOS)
• Development platform: Xcode
• SDK version: 12.0.2

Am I missing something? Does AutoGain or another parameter setting prevent configuring a manual Gain?

Thank you for helping out!

Hi ensure you have auto-gain off before attempting to manually set the gain:

solum.setParam(AutoGain, value: 0)
solum.setParam(Gain, value:  <value>)

(Sorry for the late reply, we missed this issue.)

Thank you for your reply. We found, that the probe mode setting (MSK, development, etc.) prevented setting the gain.
I would like to see a developers documentation / probe state diagrams.

Thank you for answering!

It turns out I am in the process of writing some documentation for Solum, I will take your suggestions into account thanks!
