Hi, Thank you for the suggestion. I started to build my PCB as well but I ended up desoldering the apparently broken one with a new one I bought from...

While i agree with what you have written, in my case the smart meter is RTU to the inverter which then converts the information on TCP with a different ID....

I want to also add that maybe in the code below ``` ModbusRequest::ModbusRequest(size_t length) : ModbusMessage(nullptr, length), // buffer will be set in constructor body _packetId(0), _slaveAddress(0), _functionCode(0), _address(0), _byteCount(0)...

In order to have a single class/queue i've added the following method ``` uint16_t esp32ModbusTCP::readHoldingRegisters_Meter(uint16_t address, uint16_t numberRegisters) { esp32ModbusTCPInternals::ModbusRequest* request = new esp32ModbusTCPInternals::ModbusRequest03(_serverID_Meter, address, numberRegisters); return _addToQueue(request); } ```...

I've seen the video and i've reached here. What does mean "will not fix the cells inside your battery"? Of course chemical aspects cannot be fixed with a register flip....

So it seems like that it could potentially restore the battery. Another question, the different models of DJI batteries have SDA and SCL on the external connector. In your video...

Mhmm according to this table https://github.com/o-gs/dji-firmware-tools/wiki/WM220-Battery-Intelligent-Board#external-connector-of-the-battery there is no i2c exposed to the outside? In the Mavic 1/2 mini i've seen SCL and SDA as first and last pin, can...

You mean to swap TX/RX? Also what frequency shall the i2c configured to? I'm using an odroid with debian which is quite similar to a raspberry pi but it defaults...

Isn't that i2c ? i thought the BQ30Z55 was also mounted on them. I do read a similar text on the chip I have added the GND (my bad) the...

@mefistotelis i was able to recover one of the 2 batteries i've opened up but not the second. The only different thing i did wrt to one that works was...
