i have heltec wireless stick lite, using ESP32 lorawan library provided at github/HelTecAutomation/ESP32_LoRaWAN.
i have uploaded OTAA example code with OTAA configuration to send lora packet to helium console.
is there a library can i use to receive data data packet “downlink”

ESP_LORAWAN has downlink receive and decode.

sorry but i didnt find it can u help me plz,like an example

void attribute((weak)) downLinkDataHandle(McpsIndication_t *mcpsIndication)
lora_printf("+REV DATA:%s,RXSIZE %d,PORT %d\r\n",mcpsIndication->RxSlot?“RXWIN2”:“RXWIN1”,mcpsIndication->BufferSize,mcpsIndication->Port);
lora_printf("+REV DATA:");

for(uint8_t i=0;i<mcpsIndication->BufferSize;i++)


can i use it to subscribe and publish mqtt message

Of course you can do
