Hi,
I am trying to use Tinycontrol GSM 4.2 HW=1.0, SW=1.27
Using this modbus connected to SDM72
https://aws1.discourse-cdn.com/arduino/o...7953a.jpeg
I used Serial port (tried swap)
Serial RX ---- to DI
Serial TX ---- to RO
Serial 3.3V ---- to VIN
Serial GND ---- to GND
and SDM72 A to A, B to B.
it seems OK, even on SDM72 I can see "phone" icon that it communicates, but I always get 0 values
when I try modbusread I get
I just need current power, not sure what exactly those 10 values are, but I hoped one of them is current power on all phases.
I also have made test and with USB-modbus converter I was able to read data from SDM72 with Python
Any help appreciated.
Thank you.
