The connection between the SIMCOM and the ESP32 is 115,200 baud. That could be increased (in software), and there is software flow control on the GSM MUX we use (although I have no idea if SIMCOM implements it); but without hardware flow control lines I don’t think it could/would approach 3G speeds.
Ah, I see thanks. In this case, though, the bandwidth & latency requirements are minimal ( occasional http get ) ... its not as though I want to watch youtube :-)
The alternative is to swap it around. Put the modem and the SIM in some other device designed for that purpose, and have OVMS connect to that as a WiFi client.
Right, good point, thanks. I guess I need to order one :-)

Hi All,
I've been lurking here for a while still debating wether to ditch my autopi in favour of OVMS.
One thing thats held me back is to find a way to use the wifi hotspot as a NAT router - this is useful to allow my sat nav to get traffic and charging point updates. As far as I can see on the web page this isn't currently supported.
However I did see a couple of projects that adds NAT support to lwip :
https://github.com/martin-ger/lwip_nat_arduino https://github.com/jonask1337/esp-lwip
Does anyone know if adding NAT has a fighting chance ?
Cheers,
