Bad serial link with 2.3 & SPEKTRUM SATELLITE

Post by Geebles »

Hi all,

With version 2.3 (official and latest dev build) I am using on a 328p with brushed fets. The issue I am seeing is that when "#define SPEKTRUM 2048" is used the serial link will drop 50% of packets and so become unconfigurable! The gui then updates at about 1 fps..

Here is what I usually do:

1. Unplug satellite receiver from RX port
2. Clear eeprom
3. Flash the code
4. Connect to GUI
5. Configure switches & PID
6. Disconnect serial
7. Connect satellite
8. Fly!

However when i get to step 5 it fails a lot of packets on 2.3 (WITHOUT the satellite connected!)

What i have to do now is..

1. Unplug sat
2. Flash code WITHOUT THE DEFINE
3. connect to gui and configure
4. Flash code WITH the define
5. Plug in sat
6. Fly

This is VERY repeatable with a 328p, just set the #define as above and gui will not be able to read/write values
This was NOT an issue with 2.2
