Memory setting
Sketch is supported two types of memory SRAM (by default) or EEPROM. Memory is needs to save LoRa data received.
Find and set USE_EEPROM_MEMORY constant.
#define USE_EEPROM_MEMORY false // "false" by default
Set "false" to use SRAM memory, "true" to use EEPROM.
EEPROM is permanent memory, data is not lost even if the system is turned off. But the write operation is finite and usually capped at 100,000 cycles. For more information please read: https://docs.arduino.cc/learn/programming/memory-guide
#define SRAM_STORAGE_SIZE 15 // DATA array size
Not used if USE_EEPROM_MEMORY true, may be zero in this case. NOTE: Don't use all free memory! It's may broke BLE output. You should hold free memory for return String from "sendToPhone"
Free memory size you can see in the build information.
If you enable debug mode, you can see the memory status in the Serial Monitor.
EEPROM (non-volatile) memory not used if define USE_EEPROM_MEMORY false
reserve for storing settings
#define EEPROM_BEGIN_ADDRESS 0 //bytes
Reserve part of the memory for other uses, not used if USE_EEPROM_MEMORY false
If you enable debug mode, you can see the memory status in the Serial Monitor.
