# This scripts follows old school option rules, and all
# options must come before parameters. Four parameters
# are required. Options requiring parameters must be
# followed by their parameter, with or without a space.
# Options not requiring parameters can be ganged, and may
# precede a single option requiring a parameter.

MYNAME=cdteep.sh

# Set the MTCDT EEPROM

cat <<!EOF >&2
assumptions:
All options are optional and must come first.
-b and -w require a following mac address
-d displays the PROM, do not write. Ignores other parameters.
-g GPS capability.
-l lora capability.
-i requires a following imei number
Example
cdteep.sh -lb 01:12:AB:C3:23:FE MTCDT-210L 3489235379 125-6356-2283-9792 12:34:AB:CD:8F:34
To add wifimac and remove lora:
${MYNAME} -b 01:12:AB:C3:23:FE -w 04:16:3C:C3:45:75 MTCDT-210L 3489235379 125-6356-2283-9792 12:34:AB:CD:8F:34
product-id, device-id, uuid and eth_mac_addr are required.
-d display EEPROM
-g capa-GPS
-l capa-Lora
The following fields are fixed:
out-file ${out}
vendor-id ${vendor_id}
hw-version ${hw_version}
