This is more a request for an enhancement than anything else… but could the new emlidtool specify a return code (other than zero) to indicate that the command has failed? It makes it much easier to use for scripting, rather than having to parse the output.
For instance:
root@navio:/home/pi# emlidtool test
2017-10-16 11:21:12 navio root[714] INFO lsm9ds1: Passed
2017-10-16 11:21:12 navio root[714] ERROR ms5611: Failed
-- Reason: No connection!
2017-10-16 11:21:12 navio root[714] INFO pwm: Passed
2017-10-16 11:21:12 navio root[714] INFO mpu9250: Passed
2017-10-16 11:21:12 navio root[714] INFO adc: Passed
2017-10-16 11:21:12 navio root[714] INFO rcio_status_alive: Passed
2017-10-16 11:21:12 navio root[714] INFO gps: Passed
root@navio:/home/pi# echo $?
0
This really should return with a non-zero code to indicate that something has failed.
Similarly:
root@navio:/home/pi# emlidtool rcio check
current: 0x793d141e
local: 0xcaec2284
You need to update. Please run:
emlidtool rcio update
root@navio:/home/pi# echo $?
0
Returning non-zero would make it much easier to check for this in a custom startup script, and automatically run the update.
Is this a feature that could be added?
(I’m still working through the MS5611 failure…)
Many thanks
Patrick
