DBus

I'm using the same dbus connection style to BlueZ I recently learned in my Govee project. This project does not link to bluetooth libraries directly. I've duplicated a couple of functions for handling bluetooth address structures safely.

#include <iomanip>
#include <iostream>
#include <regex>

#ifndef bdaddr_t
  /* BD Address */
  typedef struct {
    uint8_t b[6];
  } __attribute__((packed)) bdaddr_t;
#endif // !bdaddr_t
bool operator <(const bdaddr_t& a, const bdaddr_t& b)
{
  unsigned long long A = a.b[5];
  A = A << 8 | a.b[4];
  A = A << 8 | a.b[3];
  A = A << 8 | a.b[2];
  A = A << 8 | a.b[1];
  A = A << 8 | a.b[0];
  unsigned long long B = b.b[5];
  B = B << 8 | b.b[4];
  B = B << 8 | b.b[3];
  B = B << 8 | b.b[2];
  B = B << 8 | b.b[1];
  B = B << 8 | b.b[0];
  return(A < B);
}
bool operator ==(const bdaddr_t& a, const bdaddr_t& b)
{
  unsigned long long A = a.b[5];
  A = A << 8 | a.b[4];
  A = A << 8 | a.b[3];
  A = A << 8 | a.b[2];
  A = A << 8 | a.b[1];
  A = A << 8 | a.b[0];
  unsigned long long B = b.b[5];
  B = B << 8 | b.b[4];
  B = B << 8 | b.b[3];
  B = B << 8 | b.b[2];

  B = B << 8 | b.b[0];
  return(A == B);
}
std::string ba2string(const bdaddr_t& TheBlueToothAddress)
{
  std::ostringstream oss;
  for (auto i = 5; i >= 0; i--)
  {
    oss << std::hex << std::uppercase << std::setw(2) << std::setfill('0') << static_cast<int>(TheBlueToothAddress.b[i]);
    if (i > 0)

{ 
  bdaddr_t TheBlueToothAddress({ 0 });
  if (std::regex_match(TheBlueToothAddressString, BluetoothAddressRegex))
  {
    std::stringstream ss(TheBlueToothAddressString);
    std::string byteString;
    int index(5);
    // Because I've verified the string format with regex I can safely run this loop knowing it'll get 6 bytes
    while (std::getline(ss, byteString, ':'))
      TheBlueToothAddress.b[index--] = std::stoi(byteString, nullptr, 16);
  }
  return(TheBlueToothAddress); 
}

OpenSSL

I had to learn to use OpenSSL to decrypt the AES CTR blocks that are being sent by Victron. This was very quick and dirty, but works.

#include <openssl/evp.h> // sudo apt install libssl-dev

uint8_t DecryptedData[32] { 0 };
if (sizeof(DecryptedData) >= (ManufacturerData.size() - 8)) // simple check to make sure we don't buffer overflow
{
  EVP_CIPHER_CTX* ctx = EVP_CIPHER_CTX_new();
  if (ctx != 0)
  {
    uint8_t InitializationVector[16] { ManufacturerData[5], ManufacturerData[6], 0}; // The first two bytes are assigned, the rest of the 16 are padded with zero

    if (1 == EVP_DecryptInit_ex(ctx, EVP_aes_128_ctr(), NULL, EncryptionKey.data(), InitializationVector))
    {
      int len(0);
      if (1 == EVP_DecryptUpdate(ctx, DecryptedData, &len, ManufacturerData.data() + 8, ManufacturerData.size() - 8))
      {
        if (1 == EVP_DecryptFinal_ex(ctx, DecryptedData + len, &len))
        {
          // We have decrypted data!
          ManufacturerData[5] = ManufacturerData[6] = ManufacturerData[7] = 0; // I'm writing a zero here to remind myself I've decoded the data already
          for (auto index = 0; index < ManufacturerData.size() - 8; index++) // copy the decoded data over the original data
            ManufacturerData[index+8] = DecryptedData[index];
        }
      }
    }
    EVP_CIPHER_CTX_free(ctx);
  }
}

Victron Extra Manufacturer Data

Victron refers to Extra Manufacturer Data. It's all manufacturer data at the bluetooth level. What Victron refers to as "Extra Manufacturer Data" starts at the 8th byte of the manufacturer data, and runs to the end of the Bluetooth Manufacturer Data record. Decoding the extra manufacturer data, Victron bit packs the extra data before encrypting it using the AES CTR method.

Manufacturer Data

Start Byte	Byte Count	Meaning	Remark
0	1	Manufacturer Data Record type	0x10=Product Advertisement
1	2	model id
3	1	read out type	0xA0
4	1	record type	Used to decide which bit packed structure to decode the extra data. e.g. 0x01=Solar Charger 0x05=SmartLithium
5	2	AES Initialization Vector	two bytes, pad with 14 more 0x00 values to have a 16 byte array. sometimes called "nonce"
7	1	First Byte of AES Decryption Key	If this doesn't match the stored key, skip attempting to decode
8	?	First Byte of encrypted data	Extra Manufacturer Data
