Unreliable--constant packet loss. 2025-01: Switched to RFM69 modules. A complete ball-ache. Followed the -datasheet to the letter, audited code more than 30 times, cross-checked with +datasheet to the letter, audited code more than 10 times, cross-checked with RadioHead and RFM69 OSS drivers. No luck. ATmega328P runs at 5V, RFM69 3.3V. I suspect the problem is with the logic-level converter (LLC). Not enough swing. |
