Summary:

The TCXO we use (TYETBCSANF-32.000000) with the Generic Node has 2.8 to 3.3V supply range. In the radio firmware we've noticed that lower voltage of 1.7V was used. Altough it did not affect the function of the device (luckily), I believe it will improve the overall device stability.

Thanks to @rayozzie for reporting it.

What do you see now?

These are all the occurrences of this flag:
https://github.com/TheThingsIndustries/generic-node-se/search?q=TCXO_CTRL_VOLTAGE

Current setting is given below:
#define TCXO_CTRL_VOLTAGE TCXO_CTRL_1_7V

What do you want to see instead?

It would need to be changed to:
#define TCXO_CTRL_VOLTAGE TCXO_CTRL_3_0V

Environment:

VS Code, STM32CubeIDE

What can you do yourself and what do you need help with?
