Firmware Version

2.7.12 (1831)

What did you do?

New RAK4631, Using IOS 2.7.12 - scanning QR code for local mesh. Applying the config fails.

Expected Behavior

Android users tell me that same QR config works to configure their devices.
The IOS app should not error "Failed to shave channel configuration"

Current Behavior

B8B8 asserts that 0 means default, therefore when the iOS app attempts to apply TX = 0, Ch# = 0, BW = 0, CR = 0, SF = 0. it SHOULD apply the defaults (for MediumFast) EVEN THOUGH the QR code has these values explicitly set..... TX = 30dbm, Ch# = 45, BW = 250, CR = 5, SF = 11

Perhaps this is a collision with manual values and the Use Preset selector?

either way the app throws an error: Failed to save channel configuration
