Hello,
I’m developing a Central System communicating with chargers using OCPP 1.6J protocol. It communicates fine with Wallbox charger now and I wanted to append support for Teltonika charger. However test charger switched itself to “Unauthorized connection attempt” state what is unexpected.
Technical info:
Product code: EVC1200P4011
Network connection type: Wifi
Hardware revision: 000
Test scenario:
- Setup charger CONNECTIVITY following https://wiki.teltonika-energy.com/images/7/73/TeltoCharge_QUG_V2.4.pdf document.
- The OCPP URL: ws://some_lan_ip:8080/ocpp16/
- Charge point identity: CMD02
- wait for charger connection to Central System
Central System log (all messages):

I tried to identify the issue cause and the solution (mainly following the OCPP 1.6 JSON guide - Wiki document) but with no luck.
Can you tell me what’s wrong and how to solve it?
