nrf_cloud_connect failed: 22

[chapman]

Hi , 

I am using SDK v0.4.0.

Modem firmware : mfwnb1nrf9160030123prealpha

Asset tracker example is downloaded to the NRF9160-DK.

Since I am using NB IOT, I select NB-IOT in "Configure nrf connect SDK Project"

"AT%XSYSTEMMODE" is not supported by this modem firmware version, so I remove  writing this command in w_lte_lc_init_and_connect().

However, it output a error:

nrf_cloud_connect failed: 22 

which means "Invalid argument"

Do you know how to solve this problem? Thank you

Hello, you should try to upgrade the modem firmware since yours is outdated.

[chapman]

I upgraded the firmware to the latest version 0.7.0-29.alpha 

it also got a error 

nrf_cloud_connect failed:22

What  I should to avoid this error? I have tried the latest modem firmware with using at_client example which can connect to the network successfully. 

Thanks

[Hakon]

Did you run the AT%XSYSTEMMODE command?

[chapman]

yes, you can see the log, nbiot was set 

lte_lc.at_cmd: send: AT%XSYSTEMMODE=0,1,0,0

[Hakon]

Try the following,

Set AT%XEPCO=0,

AT%XBANDLOCK=1, "10010101".

[chapman]

After I set AT%XEPCO=0, it works. 

Thank you.
