arduino-rx yields garbled data #86

Closed Flamabalistic closed 1 year ago

Flamabalistic commented 1 year ago

Hello Georgi! My name is Xavier from Melbourne, Australia, and I'm interested in the data-over-sound space.

I've just received my Arduino Nano RP2040 connect and loaded your arduino-rx example code.

Some environmental info:

Issue description

examples/arduino-rx shows garbled data when sent a message from waver.

This has been tested with both the waver website and android app. Both are setup to transmit [MT] Fastest. The Arduino is set to receive GGWAVE_PROTOCOL_MT_FASTEST.

Steps to reproduce the issue

  1. Open https://waver.ggerganov.com/ and change TX protocol to MT Fastest, and Fixed-length to true, and 16 bytes
  2. Upload https://github.com/ggerganov/ggwave/blob/master/examples/arduino-rx/arduino-rx.ino onto the RP2040
  3. Open serial monitor - set to 57600
  4. Send the message 'test' using waver

What's the expected result?

Output msg: test

What's the actual result?

Output: msg: ⸮⸮⸮⸮⸮⸮⸮Eu⸮.2J_ HEX: E2 FA C7 DB 1B 91 DE C5 45 75 E8 2E 0F 32 4A 5F

Additional details / screenshot

I've been looking through the source code for a day or so without any luck. Do you have any ideas of what might be wrong? Thanks, Xavier

Just figured it out! The Arduino example uses DSS by default, whereas the waver website doesn't. Enabling DSS on waver solved it. P.S. The software as a whole works great. Keep it up!
