MVPHi Colin
Just re-tested your fine upload function and the skip chunks problem has been fixed. However you make one retraction too much when you run the curl command.
When you iterate over the file you have this calculation for the end range number: BYTES_END=$((${BYTES_START} + ${TMP_FILESIZE} - 1))
but then when you fire off the curl command you do it again:
OUT=$(/bin/bash -c "${CURL} -s --insecure -X POST --data-binary '@${TMP_FILE}' --user '${BIGIP_USERNAME}:${BIGIP_PASSWORD}' -H 'Content-Type: application/octet-stream' -H 'Content-Range: ${BYTES_START}-$((${BYTES_END} - 1))/${FILESIZE}' 'https://${BIGIP_DEVICE}/mgmt/shared/file-transfer/uploads/${2}'")
This causes the rest API to go mad:
[SEVERE][18286][17 Jul 2018 14:25:29 UTC][8100/shared/file-transfer/uploads FileTransferWorker] Transfer failed for /var/config/rest/downloads/file.txt with java.lang.IllegalStateException: Chunk byte count 499713 in Content-Range header different from received buffer length 499712

If I change it to this instead it works:
OUT=$(/bin/bash -c "${CURL} -s --insecure -X POST --data-binary '@${TMP_FILE}' --user '${BIGIP_USERNAME}:${BIGIP_PASSWORD}' -H 'Content-Type: application/octet-stream' -H 'Content-Range: ${BYTES_START}-$((${BYTES_END}))/${FILESIZE}' 'https://${BIGIP_DEVICE}/mgmt/shared/file-transfer/uploads/${2}'")
