Hall Unit is a Pb Device aka Port B Device (the connector collar tell you what port it connect to) for the Hall sensor you need a PbHub.

FWIW: here in Switzerland both URLs work for me.
RE: What is the best Dupont cable size to use with ESP32 Core and Core 2 controllers?
DuPont or 2.54 is the standees size for headers and connectors. For the ‘-Bus internal connector you need an I/o breakout board or base as the connector is shallow to save space.
RE: OTA firmware upgrades over LTE?
hmm, not sure why your sketch is taking longer (unless the firmware is bigger).
I think if you want to decouple the flash from the download process you'd need to look into examples using SPIFFS. However in my opinion this is kind of redundant as SPIFFS is in flash as well. So the download would go into SPIFFS first and then copy from flash to flash. (Unless I am missing something.)
When I check with
tcpdumpon my server I see it reading multiple small chunks over the period of the download (about 37s). In other words I don't think there is a buffer on the way or in the modem in my case.
Are you using the default
modem.restart();? I found it can take quite some time for the modem to be ready after that. Plus the modem sometimes sends some unsolicited messages (e.g.
PB DONE) as well which I think might interfere with the download.
You could try using
modem.init();instead and / or add some sort of delay / check if the modem is ready or not. I've added the following line
String modemInfo = modem.getModemInfo();which helped the download when using a SIM7600G.
BTW: from what I can tell my setup uses CGNAT IP starts with 10.x.x.x.
P.S. github example updated
