Hotspot created but cannot be discovered

Hi,
Recently I decided to switch my WIFI card from EMMY-W163 (datasheet: https://www.u-blox.com/sites/default/files/EMMY-W1_DataSheet_%28UBX-15011785%29.pdf) to WPEA-121N (https://www.sparklan.com/product/wpea-121n-ar9382-2t2r-wifi-module/). I am using a custom computer with Nitrogen6 SOM V2 (https://boundarydevices.com/product/nitrogen6-som-v2/). I use ubuntu 16.04.1LTS, kernel 4.1.15.
One of tasks I preform on this computer is to create a hotspot.
When using EMMY card, I can create hotspot using create_ap script with config:
CHANNEL=6
GATEWAY=192.168.10.1
NEW_MACADDR=
SSID=MySSID
PASSPHRASE=MYPassword
WIFI_IFACE=mlan1
WPA_VERSION=1+2
ETC_HOSTS=0
DHCP_DNS=gateway
NO_DNS=1
HIDDEN=0
ISOLATE_CLIENTS=0
SHARE_METHOD=none
IEEE80211N=1
IEEE80211AC=0
HT_CAPAB=
VHT_CAPAB=
DRIVER=nl80211
NO_VIRT=1
COUNTRY=DE
FREQ_BAND=2.4
DAEMONIZE=0
NO_HAVEGED=0
INTERNET_IFACE=
USE_PSK=0
It works without any problems. Now when I change card for WPEA and try to create hotspot using create_ap (modifying config parameter WIFI_IFACE first) I get.

I checked that WPEA card supports AP mode:
iw list
*
Supported interface modes:
* IBSS
* managed
* AP
* AP/VLAN
* WDS
* monitor
* P2P-client
* P2P-GO
*
Running create_ap on computer with WPEA card:
sudo /opt/scripts/create_ap --config /etc/opt/config/create_ap.conf
Config dir: /tmp/create_ap.wlp1s0.conf.W9XzBnhu

WPA: Not enough entropy in random pool for secure operations - update keys later when the first station connects

Low entropy warning also occurs when I run this script on EMMY card so I do not think it is causing problems with hotspot.

But wifi network cannot be found (it is also not a hidden network)
When I try to connect to other Wi-Fi, I can only connect to ones that are not encrypted. When trying to connect to encrypted ones I get:
sudo nmcli device wifi connect mynetwork password mypassword
Error: Connection activation failed: (7) Secrets were required, but not provided.
I also tried to set hotspot using nmcli/nmtui and hostapd commends, with similar results.
For me the most important thing is to use the device as a hotspot.
