Thanks Mark. A few more questions. 1. When will the schematics/component selections be published on GitHub? 2. What programming language are you planning on moving to seeing as how the PIC code will not translate directly to the ESP32? 3. Will the modem be moving to LTE Cat M1.NB1 for a little future proofing? I am toying with the idea of ordering a https://www.pycom.io/product/gpy-preorder-shipping-may-2017/ board and converting the OVMS code base+vehicle specifics to Python leveraging private MQTT. But I don’t want to fork too far away :/ Chris, Julien, I hear you. Just waiting for the latest processor stepping from Espressif, then should be ok for a run of developer boards. Still no modular certification, so stuck as a DIY until that is resolved. I appreciate that the delays are frustrating - for me too. Just a huge steep learning curve with this new platform. Regards, Mark.
