I have a device coected to IBM IoT foundation. It uses a TI CC3100 Wi-Fi chip driven by an MSP430 MCU. The device used to coect perfectly to IOTF in the past. I didn't use it for a couple of months and now suddenly it does not coect. Did IBM recently change anything in the MQTT protocol for IOTF ?
I get the following messages on the device's console:
Device is configured in default state
Device started as STATION
Coection established with AP
Broker coect failed for co no. 1
Exiting the Application
In the Watson IoT foundation dashboard I see the following messages (in the coection log):
Closed coection from 217.132.56.201. The topic does not match an allowed rule 2 times in the last 5 minutes May 29, 2016 8:36:46 AM
Closed coection from 217.132.56.201. The topic is not valid. 2 times in the last 5 minutes
Can anyone help resolving this problem ?
Thanks a lot, Day
