Hello I am using RAK2461 and configuring it through IO Box and have added 2 Modbus Poll tasks. The device is connected to a ultrasonic sensor where I need to measure air speed and air direction simultaneously before the data is transferred to Loriot.io. Channel 1 is for air speed while channel 2 is set to air direction. Right now when I receive the data in Loriot.io, it is only received as channel 1 and channel 2 does not send through. Is there any possible way to enable multi channel uplinks?
Welcome to RAK forum @Mikael ,
On the polling tasks, are the sensor values on the channel 1 and channel 2 correctly captured by IO.box? Also on your LoRaWAN settings, is ADR active?
Yes they are both correctly captured and ADR is active. Here is a photo of how the data received looks. I was expecting a 01 and a 02 but I am only able to receive the 01.
Aren’t these the payload?
Good observation. Thank you so much for pointing out. Now if I may inquire why is this 01 separate to the 03 and not able to combine even when the SF is down to 7?
This is a known limitation with the current Bridge IO firmware. The next release is optimized and will squeeze the number of polled payload on what’s allowed on the SF being used.
