Example: POS Settings

# POS Login

Odoo Server: http://pos.severinsealodge.com:8069 (Not Secure)

Use a HTTP connection when using the Odoo iOS Application, since there is a problem with the SSL Certificate provided be the IoT Box.

POS Login

More info bellow.

# HTTPS Problem

Whe connecting to Odoo over a secure connection (HTTPS) the POS Software tries to connect to the IoT Box also over HTTPS.

The problem is that the iOS Device isn't trusting the Odoo Signed Certificate provided by the IoT Box, and that's the reason that the printer isn't found.

When using a HTTP connection there is not certificate to cause trust issues between the IoT Box and the iOS Device.

# Trusting the IoT Certificate

You can download the IoT Certificate and install it on the iOS Device.

  1. Email the certificate to yourself and then tap on it.

  2. Go to settings and install the certificate.

  3. Last go to Settings > General > About > Certificates and enable full trust.

Event after completing the above steps and trusting the certificate provided on the iOS Device your POS Client still won't be able to react the IoT Box over HTTPS. As a way around a HTTP connection should be used.
