Hi,

Unfortunately, we don't have any new UV sensors. For ambient light sensors, you can use Si1153 instead.

It's unlikely that you're getting an accumulation overflow with SW_GAIN set to 1. So basically, one channel's measurement has saturated in your test. You shouldn't change the SW_GAIN setting, but instead, you should reduce the sensitivity of the sensor to avoid saturation. For example, setting HSIG to 1 in outdoor applications to avoid saturation.

I'm not sure why you're getting this weird behaviour. Did you accidentally set COUNTER_INDEX in MEASCONFIG register? Can you post your configuration code?

Are you asking about SAW1 and SAW2? You can use other GPIO pins in your design but on the radio board, you can't make any changes.

I think there's some misunderstanding about the terminology, but anyway, if a slave node is out of direct range of the controller which requires multiple hops to deliver the message. It either relies on the response route (received frames carry information on the route the response has to take back), or the controller can assign return routes to the slave so that it can send unsolicited messages.

So are you asking about how to assign return routes from the controller to a slave node?

I re-counted the pulses in the capture and there is the NACK at the edge of the last clock pulse but didn't hold long enough. A couple of things you can try:

1. Reduce the I2C frequency and see if that helps.

2. Increase the pull-up resistor on the I2C bus.
