Hello,
I did some tests using the same node (heltec stick lite) one using LoRa, the other one using LoRaWAN, I had best result using LoRa.
I was using a GPS connect to the module to get the coordinates and analyse my RSSI.
The first point is with LoRa I was able to use SF = 11 , in LoRaWAN for US915 I realize that the maximum SF is 10. The second point, how can I know if the power is setting to the max using LoRaWAN? Using LoRa was easy, just a direct function. As LoRaWAN has adr I guess is more complicated, I want to put the max as default. Loking the docs, the RegionUS915.h I found this:
/*!
- Minimal Tx output power that can be used by the node
*/
#define US915_MIN_TX_POWER TX_POWER_10/*!
- Maximal Tx output power that can be used by the node
*/
#define US915_MAX_TX_POWER TX_POWER_0/*!
- Default Tx output power used by the node
*/
#define US915_DEFAULT_TX_POWER TX_POWER_0
TX_POWER_0 is the max I guess. Because I found this on Region.h:
/*!
- Region | dBM
- ------------ | :-----:
- AS923 | Max EIRP
- AU915 | Max EIRP
- AU915_SB2 | Max EIRP
- CN470 | Max EIRP
- CN779 | Max EIRP
- EU433 | Max EIRP
- EU868 | Max EIRP
- IN865 | Max EIRP
- KR920 | Max EIRP
- US915 | Max ERP
- US915_HYBRID | Max ERP
*/
#define TX_POWER_0 0
Do I need to do anything else in order to be sure that I’m using the max power?
