Hello Champs,
Customer still has the problem which I have posted before.
https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1174043/iwr6843-point-cloud-tlv-parser-failed
The line331 in oob_parser.py prompted an error.
def parseCapon3DPolar(self, data, tlvLength):
pUnitStruct = '5f' #elev, azim, doppler, range, snr
pUnitSize = struct.calcsize(pUnitStruct)
pUnit = struct.unpack(pUnitStruct, data[:pUnitSize])
data = data[pUnitSize:]
objStruct = '2bh2H' #2 int8, 1 int16, 2 uint16
objSize = struct.calcsize(objStruct)
self.numDetectedObj = int((tlvLength-pUnitSize)/objSize)
#if (self.printVerbosity == 1):
#print('Parsed Points: ', self.numDetectedObj)
for i in range(self.numDetectedObj):
try:
elev, az, doppler, ran, snr = struct.unpack(objStruct, data[:objSize])
