I’m currently using a RAK3172 as a node, connected to a Raspberry Pi with a DHT11 sensor that sends data to my RAK5146 gateway. The gateway is configured with Local Chirpstack V4, and the data is sent via LoRa. I’m facing an issue where the data sometimes reaches the gateway, but other times it doesn’t.
The node is currently sending data every 35 seconds. My question is: is this interval appropriate, or should I adjust it? What other factors should I look into to ensure consistent data reception?
Finally, I want to mention that I am using the US915 frequency band.
Any advice or recommendations to improve the stability of data reception would be greatly appreciated.
In this example, I have 7 transmissions, but only 3 were received.
What is the TX power you use on the RAK3172?
How far or close to each other are the node and the gateway?
What RSSI and SNR levels do you see on the gateway side?
@beegee I made the change to AT+TXP=5 and saw an improvement, but there are times when it sends the message and other times when it doesn’t. In this case, what can I do?
This is very relevant.
Did you update the firmware on the Breakout Boards? If yes, what firmware did you use?
What do you get when you send the AT command AT+VER?
It is normal that you see messages from other nodes. All LoRaWAN nodes that are in range of your gateway/RAK5146 and are using the same LoRaWAN regional settings, will be showing up in your log.
Regarding “received Join Accept but no messages”, is your node sending packets after it joined the network?
