I am trying to set up a simple Flash app to receive sensor data from a microcontroller.

Simplified code:

from flask import Flask, request, jsonify, abort, render_template

from LogFactory import log
from Database import Database
from ApiHandler import ApiHandler

app = Flask(__name__)
wsgi_app = app.wsgi_app

api = ApiHandler()

@app.route('/api/record', methods=['POST'])
def record_data():
    [b]log.info(request)[/b]
    return api.RecordSensorData(request)

if __name__ == '__main__':
    app.run('0.0.0.0', 5555, debug=True)

When I POST data to this endpoint with the Microcontroller on the same network it works fine and request.json contains the correct JSON structure. However when I connect the microcontroller through a WiFI extender I am getting some odd results, specifically request is None.

Output: * Serving Flask app "IotServer" (lazy loading)
 * Environment: development

Is there any way of seeing the complete raw post before flask tries to process it? Or anyone have any idea why this could be?

Thanks.
