Here is a quick code sample to get next and/or previous post of WordPress post if you have the post id using Awesome Studio.

   [aw2.get prev_post post_id='{post.ID}'  set='module.prev_post_id' /]
   [aw2.get next_post post_id='{post.ID}'  set='module.next_post_id' /]
     
      [aw2.set module.prev_post=''/]
     [aw2.query get_post post_id='{module.prev_post_id}' set='module.prev_post' not_empty='{{aw2.get module.prev_post_id}}' /]
     
 
     [aw2.set module.next_post=''/]
     [aw2.query get_post post_id='{module.next_post_id}' set='module.next_post' not_empty='{{aw2.get module.next_post_id}}'  /]


      [aw2.template next_post_t]
        [aw2.if cond="{{aw2.get module.next_post}}" not_equal=""]col-sm-offset-1 col-sm-5[/aw2.if]
      [/aw2.template]
      
      [aw2.template prev_post_t]
        [aw2.if cond="{{aw2.get module.prev_post}}" not_equal=""]col-sm-5[/aw2.if]
        [aw2.if cond="{{aw2.get module.prev_post}}" equal=""]col-xs-offset-1[/aw2.if]
      [/aw2.template]
      
       [aw2.if cond="{{aw2.get module.prev_post}}" not_equal=""]
         [aw2.client style]
         div.col-xs-offset-1.pag-next{
           border:0;
         }
         [/aw2.client]
       [/aw2.if]
       
      [aw2.if cond="{{aw2.get module.prev_post }}" not_equal=""]
      <div class="col-xs-offset-1 col-xs-10 [aw2.run templates.next_post_t /] pag-prev" 
           data-matchheight='[aw2.get module.post_unique_class]'>
             
        <p class='text-center'>
          <span class='font-size-smaller gray-light text-uppercase'>Previous Post</span> <br />
          <a href="[aw2.get module.prev_post.url /]"
             class='font-size-larger gray-darker'>[aw2.get module.prev_post.post_title /]</a>
        </p>
      </div>
      [/aw2.if]
      
       [aw2.if cond="{{aw2.get module.next_post}}" not_equal=""]
      <div class="col-xs-10 [aw2.run templates.prev_post_t /] pag-next" 
           data-matchheight='[aw2.get module.post_unique_class]'>
          <p class='text-center'>
            <span class='font-size-smaller gray-light text-uppercase'>Next Post</span> <br />
            <a href="[aw2.get module.next_post.url /]"
          	 class='font-size-larger gray-darker'>[aw2.get module.next_post.post_title /]</a>
          </p>
      </div>
      [/aw2.if]

1. Given a post_id you can get the next & prev post using  prev_post & next_post as shown in line 1 & 2 above.
2. Line 5 & 9 is used to get the actual post object from the post_id we got from line 1 & 2
3. Template next_post_t and prev_post_t are used to handle the situations when we are on first or last post.
4. 29 -39 & 41-50 is basically used to show the title of the next and previous post.
