next would probably be figuring out how the mt7628 "mainboard" talks to the LTE modem, it seems like there's custom firmware that exposes just an RNDIS ("usb networking") interface, through which you're supposed to connect to a MQTT server on it
the funniest thing is that the modem (MSM8909, a.k.a. Snapdragon 210) is WAY more powerful than the MT7628/MT7688 on the mainboard, besides having 8x the RAM and 250x the storage
MT7628 goes on shitty $15 routers, SD210 goes on (very low end) Android smartphones

The Qualcomm Snapdragon 210 MSM8909 is an entry level SoC for Android based tablets and smartphones. It contains four ARM Cortex-A7 CPU cores (quad core) with a clock rate of up to 1.1 GHz, an Adreno 304 graphics card, an LPDDR2/LPDDR3 memory controller (max. 533 MHz), a eMMC 4.5 port, and a LTE Cat 4 radio module.
The performance of the Cortex-A7 cores is rather low and positioned in the entry level of 2015. In our tests of the CAT S40 smartphone, daily tasks and browsing however imposed no problem for the SoC.
The integrated Adreno 304 graphics card is clocked at 400 MHz and also positioned in the entry level. Therefore, demanding games may not run smoothly in high settings.
The integrated video engine allows the encoding and decoding of 1080p H.264 videos and decoding of H.265 videos. The main display can be driven with up to 1280x720 Pixels.
The SoC integrates Bluetooth 4.1 + BLE, 802.11n (2.4 GHz) WiFi, and a Cat 4 4G-LTE-Modem (LTE FDD, LTE TDD, WCDMA (DC-HSDPA, HSUPA), CDMA1x, EV-DO Rev. B, TD-SCDMA and GSM/EDGE) with a max. speed of 150 Mbps.
you cannot do any of these on the MT7628
starting to realize that they might've actually been running all the logic (like, voip, talking to their servers, etc) on the modem itself
which means I'll have to figure out how to root the modem too

now i just have to solder the joints up and wrap everything up in fabric tape
...and maybe get some proper wire stripping tools, apparently solid copper is quite a bit harder than my fingernails?
this will go into a car for tapping 3 of the CAN buses + 2 for ground and power, for telemetry and control (not the driving kind)

zhongfu's inane ramblings

newsflash: I'm stupid and there's a newer version of the app
