So I've been working on a prototype using the compute module. Board design is in its 1st version and I'm already at work designing the refined 2nd version. During the rework I noticed a bit of issue when it comes to connecting to the compute module in order to monitor its progress. Originally I was going to use wireless on the custom PCB in the form of the ESP_Wroom_32 following this guide
which uses the ESP8266 to allow me to perform headless monitoring; however later down the line I realised I won't be needing wireless with my prototype but the bluetooth chip or equivalent that the ESP_Wroom_32 uses and thus have had to look for an alternative option to monitor the Compute module 3. I was thinking as I already use a USB micro to power/recharge the battery, it could also be used an way for me to connect directly to an host computer that could do the recharging but also allow me to access either an terminal or GUI executable and allow me to monitor / modify any scripts.
I saw talks on a previous thread
that this could be possible on a RPI model A using an adafruit cable or another form of cable which then allowed the board to be powered whilst simultaneously accessing an serial interface to monitor the RPI; however this is not the solution I wish to use but rather would like to know if there is a way that I can simply use a single usb micro and plug into a host computer and perform a headless connection to allow myself to open a GUI whereby I can monitor/modify the Compute module for troubleshooting.
If this is not possible on just a singular usb micro cable then what alternatives could I potentially look toward minus the ones I've already posted about. Preferably I want to be as headless as possible using a singular cable.
