Hello everyone,
I am facing a problem reaching the maximum output power with the LoRa E5 module. I have tested with two different spectrum analyzers, and the results are the same. Although I have set the output power to +22 dBm in the software, both spectrum analyzers only show +11 dBm. The development board I used for testing is the LoRa-E5 Dev Board. To rule out any potential issues, I made sure to test with two separate LoRa-E5 Dev Boards. Additionally, I performed all tests at the 868 MHz frequency.
While writing the software, I used the example from this repository as a reference. To observe the results more easily on the spectrum analyzer, I configured the parameters as follows:
#define FSK_FDEV 50
#define FSK_DATARATE 500
#define FSK_BANDWIDTH 500
I would appreciate it if you could help me with this issue.
