MQTT trouble (mqtt_simple & asset_tracker)

Question

Hello, 
 
 I am working on a custom PCB with nrf9160 capable of getting good signal (tested using 'at_client' sample) and all is well on the hardware. 
 I am currently working on sending and receiving messages using mqtt and I am facing issues mostly because I am new to LTE devices. 
 
 I have 2 issues which possibly relate to each other: 
 
 1. I have uploaded 'asset_tracker' onto my PCB and I get error -111. I think this is due to certifications required to connect to nrf cloud. Please confirm or correct me. 
 
 2. I tried using 'mqtt_simple' but compiler cannot find reference to ' net_addr_ntop(family, src, dst, size);' in 'socket.h'. How can I fix this issue? 
 
 Thank you

Hi,

1. I have uploaded 'asset_tracker' onto my PCB and I get error -111. I think this is due to certifications required to connect to nrf cloud. Please confirm or correct me. 
 This is correct. Only development kits have nrf cloud certifications preloaded onto the nRF9160. 
 
 2. I tried using 'mqtt_simple' but compiler cannot find reference to ' net_addr_ntop(family, src, dst, size);' in 'socket.h'. How can I fix this issue? 
 It sounds like the "nrf" revision is not compatible with the other repositories it depends on. When updating "nrf", you also need to run "west update": 
 cd ncs/nrf 
 west update 
 
 Could you try this, then rebuild the sample? 
 
 Kind regards, 
 Håkon

We have had issues wrt. ordering of compiled object in SES versions (v4.16 and v4.18), so in these versions you might have to recompile. 
 Could you try the latest SES version and see if this works better?
