my code is

void SCI::sendMultiSrc(const uint16_t packetType, const int sourcesCount, ...) {
    LOG_INF("SENDING2!");
    va_list argsList;
    if (bluetooth.connection) {
        va_start(argsList, sourcesCount);
        LOG_INF("HAVE CONN2!");
        bluetooth.sendMultiPacket(bluetooth.connection, packetType, sourcesCount, argsList);
        va_end(argsList);

        return;
    }```
