RCV Time and RFV Time requested to JK developers today

[txubelaxu]

I have sent this email today to JK:

Hi,

Sorry but, when I sent this message via web form, a message in chineese appeared, and I do not know if it was correctly sent. Here is the message:

We are a group of people testing a new monitoring solution. We have:
JK-PB2A16S-20P, hw 14.XA, sw 14.20
hw. 15 as well

I am developing this code. It is beta version but very functional (tested OK with 7 BMS in the same network).

I would like to know if the RCV Time (H) and RFV Time (H) could be available in the data found in "settings type frame" sent by each BMS.

We see that is sent in Bluetooth frames (JK app shows it and is changeable), but RS485 internal network has not this info. We have not been able to detect it.

Where is this info (RCV Time and RFV Time)? If is not in the RS485 internal network frames sent by BMSs, could you insert them in your next version, please?

The recieved "bms settings type frame" is this:

Many Thanks in advance,

Well... no answer at all from JK. But I have got a way to obtain those params from slaves (acting as pseudo master). Impossible for me to obtain that info (frame type id=3) from master (address 0x00). But obtained for slaves.
The only way I have found is setting all BMS in slave mode and set de ESP acting as Master.

Next step: setting up the ESP to communicate with Inverters.
