FAQ Field

This is for us to summarise some of the main issues when working with our loggers and sensors in the field...

"Sketch uses 8558 bytes (26%) of program storage space. Maximum is 32256 bytes. Global variables use 872 bytes (42%) of dynamic memory, leaving 1176 bytes for local variables. Maximum is 2048 bytes. avrdude: ser_open(): can't open device "\\.\COM13": Access is denied. Failed uploading: uploading error: exit status 1" That was fixed by closing the serial monitor.

Corrie’s trouble shooting steps for a radar velocity sensor that randomly stopped logging:
1 – Unplug battery
o Ensure battery is > 3.7V, if not likely dead battery issue
o Ensure all connections are secure and no short circuits are occurring, if issues correct based on https://www.bosl.com.au/wiki/Getting_Started_With_the_Radar_Sensor#BoSL_logging_firmware_adjustables
o Ensure no water in the case
o Ensure no corrosion on BoSL board and no damage to sensor
o If hardware issue discovered replace damaged components and ensure case is waterproof

2 – Plug charged battery in, and press reset for 1 second
o Allow ~ 70 seconds after long press for the website to receive the new upload
o If it begins uploading replace all components to their regular locations and wait for 1 logging interval to ensure it continues logging

3 – If these fixes only work short term or don’t work
1. re-upload BoSL logger simbase, available from link in step 1 (ensure board is on insulating surface)
2. Replace antenna with larger one, if installed in pit consider drilling the antenna out of the pit if largest antenna fails
3. Replace all equipment, potential for faulty hardware
