Hi brocaar we are observing that as we increase the payload size more than 51 from the end-node code. Mosquitto is not able to receive the data…!! is there any limitations in size of mosquitto??
Mosquitto does not have any limitation with regards to the payload size (nor does LoRa Server). Your node does however. Depending your region and data-rate, your node might not be able to the amount of data that you’re trying to send. For downlink, LoRa Server validates if the payload size is allowed, if not it is discarded and an error is logged.
Please refer to the LoRaWAN Regional Parameters document for more information: https://www.lora-alliance.org/lorawan-for-developers
