Downlink Message (RSSI)
Posted: Thu Nov 19, 2015 5:44 pm
Hello,
I have setup a dowlink message pretty quickly in my custom FW, and worked, which is great !! and I have some questions:
I would like to know the RRSI at the TD module when receiving the DL message, so I have used the following function:
int TD_SIGFOX_DOWNLINK_GetRSSI ( void )
which claims to
Return the SIGFOX down-link RSSI value latched during sync reception.
ReturnsReturns the SIGFOX down-link RSSI value in dBm.
Is it really the RSSI of the signal recevied at the module? or is it the RSSI at the Base station from the former UL message?
what I do not understand is why this value can arrive at the SIGFOX backend right after of the ACKNOWLOEDGE if no UL message is sent. I have a callbak configured in the backend so I receive an e-mail everytime I got an UL message, but no email after the DL message arrives to the TD module.
Is the DOWNLINK process sending this internally after receiving the DL message?
FYI: I have used the following function:
TD_SIGFOX_SendV1(MODE_FRAME, false, frame_START, 12, 2, true, false);
One more question:
Is it 2 good retry value for DL messages?
Regards, Ramon.
