C++ (Cpp) smartstrap_attribute_end_writeの例

コード例 #1

ファイル: strap.c プロジェクト: isabellacmor/pebblepup

void ping_arduino(char* key) {
  // Declare a buffer to be used
  size_t buff_size;
  uint8_t *buffer;

  // Begin the write request, getting the buffer and its length
  smartstrap_attribute_begin_write(attribute, &buffer, &buff_size);

  // Store the data to be written to this attribute
  snprintf((char*)buffer, buff_size, key);

  // End the write request, and send the data, expecting a response
  SmartstrapResult r = smartstrap_attribute_end_write(attribute, strlen((char*)buffer), false);
  if(r != SmartstrapResultOk) {
    APP_LOG(APP_LOG_LEVEL_ERROR, "---Smartstrap error: %s", smartstrap_result_to_string(r));
  }
