JBD BMS Wi-Fi Module

[melkier]

I would like to print the PCB to have a better quality hardware.
Normally I use PCBWay, they are cheap and fast.
Here the design.
Let me know what do you think
@melkier the project is your can I print them?

Of course you can! If you make a good one, please post your build instructions so others can use PCBWay too.

yes ... great BMS, too bad no docs on how to set parms. I have an agent for it (publishes to MQTT):

you might also look at jblance's stuff

He has a python script which can pull from the JIKONG

Try the debug option.
See if the debug reveals any clues.
Does the tty device you want exist?
What is the fully expanded command line incantation you are using?

I Don't now....

I Don't now....

Jbdtool -t bt mac adress -r-a

I had a similar error with bluetooh transport.
@melkier give me a binary executable that worked.
Try with a straight up serial connection.
also adding "-d 3" to the arg vectors.

 

[NICOLAE]

Nothing yet ?

 

[John Frum]

Please attach the full debug output as a code block.
Also you using the bluetooth transport, try the serial transport.
finally after the command returns run "echo $?" to see the return code.

 

[NICOLAE]

You don't now ... very difficult in linux. Thx

 

[NICOLAE]

This is all debug

Run and this substitute <your_mac_address> for your mac address

`jbdtool -t bt:<your_mac_address> -J -d3 >> /tmp/results.txt 2>&1`

attach results.txt to your next post.

 

[NICOLAE]

Thx again. I spend a lot of time with these.

guys he might not be using a JBD BMS

In his first post, he says: "jk bd6a20s 10p bluetooth is BLE? THX"

Oops missed that.

Ups . Is meaning this bms not working with this sw ?

@melkier here PCB arrive from PCBWay.
Super nice and very good to use it.
