Morning, I am trying to send a downlink from chirpstack server to the ESP32 v3 and I want to receive an ack from the board immediately, it is possible? I tried but i can’t, what can I do? I’ve used this sample code: https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/tree/master/esp32/libraries/Heltec-Example/examples/LoRaWAN/LoRaWan
Thank you in advice.
