Connection to server successful, first measurement apparently, also, but then, it fails.

Ubuntu 22.04 Exploration tool client (ET): 7.12.1 Server(RSS): a121-v1.8.0 Python: 3.10.12 Hardware: Sparkfun XM125 breakout board

I can download the server to the STM32, the exploration tool successfully connects, but when I start Sparse IQ (or any other tool), I get assumably one sample (I see reasonable data), but then, I get the following error message.

I don't assume this is related to the SparkFun hardware. If there was any discrepancy to the XE125, I could not connect in the first place. Also, the log "RuntimeError: Cannot decode header bytearray(b'"result_info":[[{"tick":11772,"data_saturated":false,"temperature":30,"calibration_needed":false,"frame_delayed":false}]],"stat":"ok","payload_size":192}\n')" Doesn't look like a hardware issue to me
