I'm struggling to setup communications between two 868 MHz sub-GHz modules.
The first module is the STEVAL-IDS001V4M (USB dongle with SPSGRF-868) and the second module is the STEVAL-SP1ML868 (USB dongle with SP1ML-868).
I'm using the Windows application 'SPIRIT1 DK Application v2.2.1' to configure the radio and packet settings of the STEVAL-IDS001V4M module, then using the 'Transmission Test' window to send the text 'Hello World'.
The radio and packet settings for the STEVAL-IDS001V4M are as follows (configured via the GUI):
Frequency Base: 867.999967 MHz
Data Rate: 38.433 kbps
Frequency Deviation: 19.836 kHz
Channel Filter: 102.115 kHz
Output Power: 0 dBm
Packet Format: BASIC
Preamble Length: 4
Sync Length: 4
Sync Value: 0x88888888
CRC: No CRC
Data Whitening: Enabled
The radio and packet settings for the STEVAL-SP1ML868 are as follows:
The data received from the STEVAL-SP1ML868 is:
Something is being received but not 'Hello World'.
I assume the two dongles are compatible? They both use the SPIRIT1 module.
I'd be very grateful if anyone can help or provide any suggestions.
