[saphcp] [iot] Create IoT applications with SAP Cloud platform & Tessel kit - Common Issue & Solution

Hi,

You can follow the full tutorial here:
https://www.sap.com/developer/how-tos/2016/09/iot-tessel.html

However, you may get some issue during following the tutorial (as I did), then come to this post to find the answer:

Cannot use the Ambient module: attempt update but running forever

Reason: Still not sure why this happening. But based on Tessel GitHub page, the reason may come from the old firmware of the Tessel board & the ambient module.

Solution: this is a workaround for now. Instead of connecting the Ambient module to Port A of Tessel board. Connect it to PORT B of the board. Remember to change the JS code in the ambient.js also.

The Tessel board & module should be set up like this

1. The 'iotmms' application has status "Starting" forever

Reason: The application needs to bind with one database in Hana cloud. But it seems that the tutorial did not mention clearly about this prerequisite.

Solution: Add a schema name "myhanaxs" into your sap cloud platform database system. Manually add the binding between your newly create database & the application 'iotMMS'.

Select Binding ("1 available") inside the database

Add "New Binding" to the database, link to 'iotmms' application

Error 403: Forbidden when accessing the 'iotmms' application

- Assign the required role to your account (follow tutorial)

- Clean the cache & restart browser before re-access the app. (It's better to use another browser to completely reset the session).
