APPENDIX : SERVICE COMMANDS
Services commands are used to configure Wavecard modules or to read radio parameters independently of
the connected host equipment. No data is sent to the connected host when a Wavecard recognizes a service
command.
These commands are mainly used to handle:
• Link budgets with remote modules (RSSI levels)
• Verifying products firmware version remotely,
• Setting or reading parameters via RF (not described here)
