Minimal P1 Modbus Dongle firmware version for using with the Teltonika TeltoCharge = 1.2.1
update instruction : update
The default settings are:
Modbus device id: 43
RS485 : 8E1 38k4 bps (8 bits, even, 1 stop, 38400 baud)
P1: 115200 8N1 = SMR v4 and v5 (EU) smart meters. Older smart meters (in the Netherlands v2/v3) use a additional power supply for the modbus dongle and FC06 register 6 should be true (1).
The Dongle supports FC03 and FC06 registers.
All registers are :
uint32 (4321) values
N/A = 0xFFFFFFFF
Registers 10, 12 and higher are implemented in firmware version 1.2.0+. Registers 38 - 48 are available from version 1.2.1.
| register | desciption | unit/value |
