Spirit1 868 MHz problem with communication with SP1ML

Marcin Mróz

Hello,

I have problem with transmitting data from Spirit1 to SP1ML USB dongle module. Al registers are exactly the same on both modules. No matter what I'm sending (via Spirit1) 96 byte ASCII string or even 8 byte one on receiving side (SP1ML) i get 192 bytes of random data. What could be wrong with my initialization procedure?

So far my initialization procedure is quite simple and contains:

  1. Check if ID number is correct
  2. Writing data to configuration registers
  3. Flushing TX FIFO with flush TX command
  4. Sending string of ASCII characters to TX FIFO
  5. Checking if massage that FIFO contains have correct size
  6. Transmitting data with TX command

Am I doing something wrong or missing something? Let me know. Thanks in advance.

Best regards.
