SIM7600 Powerkey/reset
Posted: Fri Jul 26, 2019 5:39 pm
I have an issue with a seemingly dead SIM7600.
I received a Freematics One+ during the week and the pre-installed firmware seemed to work fine - I recall seeing the IMEI being printing and sending packets so I am satisfied the shipped unit was not DOA.
However from there I have uploaded various different firmware (such as the telelogger via the Freematics Builder) and none have woken up the SIM7600.
It seems as if the LOW/HIGH sequence on pin 27 is not waking up the module.
Has anyone experienced this?
Is the shipped firmware EXACTLY the same as whats on Github?
I notice other simcon projects connect also the RESET line on the SIM7x00 - which apparently can be used to reset/wake the module if the normal powerkey process doesnt work. Is this connected on the xBee?
