There's a problem with soil moisture and voltage. Need help.

[t9080]

I have soldered it five times, but I don't know why the soil moisture is always 100%, and the battery voltage is 0.007 or 0.001v.

Hey @t9080,

My first guess is that the firmware was compiled for a different board revision. Earlier revisions use a different battery measurement pin and different moisture configs. This would explain why other sensors work but not these two. Double check you're selecting the correct board and revision (1.2.0, 2.0.0 etc).

Otherwise, to rule out hardware issues, does this happen with a single board or multiple boards? Do the logs say anything?

[t9080]

thank you

I tried to recompile, but I still encountered a problem and tried to solve it.

[t9080]

Please send me a firmware for me to test whether there is a problem with the hardware.

Make sure to select the 2.7.0 sdk. Or build with docker: https://github.com/rbaron/b-parasite/wiki/How-to-Build-the-Firmware-Samples

Also make sure to select the b-parasite board and revision. In your screenshot you're building for the nrf52840 dev kit.

谢谢你的回复，我始终无法找到 b-parasite 开发板

Make sure you follow the wiki.

If using VSCode, you have to open ble.code-workspace, so it also imports the board definitions.
