thank you sir for this amazing project and all support you provided earlier.
Currently i am facing a issue regarding sleep current of lora module, it should consume 2uA current in sleep mode, but i am getting 100uA current on my multimeter with stm32l051 and Ebyte E22 400m22s, with only stm32l051 i am getting 4uA max, but with Lora it increases to 100 uA.
code:
#include "STM32LowPower.h"
#include <RadioLib.h>
SX1268 radio = new Module(PA4, PB13, PB15, PB14);
// save transmission states between loops
int transmissionState = RADIOLIB_ERR_NONE;
// flag to indicate transmission state
bool transmitFlag = false;
// flag to indicate reception state
bool receiveFlag = false;
//time when receive flag got activated
unsigned long receiveflagStart = 0;
// flag to indicate previous scan state
bool prevScanFlag = false;
// flag to indicate that a packet was received or transmitted or channel scan
volatile bool scanFlag = false;
void setFlag(void) {
// we sent or received a packet or scanned channel, set the flag
scanFlag = true;
}
void setup() {
//pinMode(LED_BUILTIN, OUTPUT);
// Configure low power
delay(10000);
radio.begin(433.5, 62.5, 9, 5, 0x34, -9, 8, 1.6, false);
radio.setCurrentLimit(140);
radio.setCRC(true);
// set the function that will be called when new packet is received
radio.setDio1Action(setFlag);
LowPower.begin();
}
void loop() {
//LowPower.sleep(5000);
radio.sleep();
LowPower.deepSleep(10000);
radio.standby(RADIOLIB_SX126X_STANDBY_RC, true);
delay(5000);
}
i an designing a wireless node on aaa battery to last for 2 years, with 100uA sleep current, its not possible. please help sir
