Hi, I can't believe this without connecting IRQ pin I'm getting following data....

Device ID: DECA - model: 1, version: 3, revision: 0 Unique ID: FF:FF:FF:FF:00:00:00:00 Network ID & Device Address: PAN: FFFF, Short Address: FFFF Device mode: Data rate: 6800 kb/s, PRF: 16 MHz, Preamble: 128 symbols (code #4), Channel: #5 Device ID: DECA - model: 1, version: 3, revision: 0 Unique ID: FF:FF:FF:FF:00:00:00:00 Network ID & Device Address: PAN: FFFF, Short Address: FFFF Device mode: Data rate: 6800 kb/s, PRF: 16 MHz, Preamble: 128 symbols (code #4), Channel: #5

Hi, i did some tests with dwm1000 below are some result....

with all pin connected i'm getting----> Device ID: DECA - model: 1, version: 3, revision: 0 Unique ID: FF:FF:FF:FF:00:00:00:00 Network ID & Device Address: PAN: 0A, Short Address: 05 Device mode: Data rate: 6800 kb/s, PRF: 16 MHz, Preamble: 128 symbols (code #4), Channel: #5

  1. when i removes IRQ pin then i'm getting same result.
  2. after removing IRQ pin and RESET pin i'm getting ---> Device ID: DECA - model: 1, version: 3, revision: 0 Unique ID: FF:FF:FF:FF:00:00:00:00 Network ID & Device Address: PAN: FFFF, Short Address: FFFF Device mode: Data rate: 6800 kb/s, PRF: 16 MHz, Preamble: 128 symbols (code #4), Channel: #5

PAN and Short address changed.

I can't believe after removing IRQ, RST and VCC 3.3V I'm getting Device ID: DECA - model: 1, version: 3, revision: 0 Unique ID: FF:FF:FF:FF:00:00:00:00 Network ID & Device Address: PAN: FFFF, Short Address: 05 Device mode: Data rate: 6800 kb/s, PRF: 16 MHz, Preamble: 128 symbols (code #4), Channel: #5 Device ID: DECA - model: 1, version: 3, revision: 0 Unique ID: FF:FF:FF:FF:00:00:00:00 Network ID & Device Address: PAN: FFFF, Short Address: 05 DeöDW1000 initialized ...

I pressed reset button...you can see Device Id become BC95 and suddenly DECA. If i remove any SPI pin then device id becomes 00 Don't know what happening, i tried with another decawave set up too. I'm programming arduino pro mini using Arduino UNO.

Hi @Rotzbua , I uploaded BasicSender code in Pro Mini without connecting IRQ and RST pin I'm getting following on serial monitor....

Hello, I'm trying to set basi connectivity test with a pro mini.But i'm getting just random characters (squares) in te serial monitor. Broad rates and all stuffs has checked.
