Mos wifi error ESP8266-01

General
1

Hi there,

I’m new to the mongoose OS platform and I’ve got some issues with the “mos wifi” command.

I’m using a ESP8266-01 module with 1Mb of flash memory.
As test I’ve created the demo app (mos clone https://github.com/mongoose-os-apps/demo-js app1).
I’ve added the FLASH_SIZE: 1048576 to the mos.yml file before making a build of the app.
Afterwards I’ve flashed to ESP8266 module.

Everything works fine but when I try to configure the wifi connection with the command: mos wifi WIFI_NETWORK_NAME WIFI_PASSWORD, I’ve receive the following message:

$ mos wifi
Error: /private/tmp/mos-20200204-9510-12i29jp/mos-18c19395db3292985b1d067c4188efd91eea62d3/go/src/github.com/mongoose-os/mos/cli/wifi.go:33: Usage: /usr/local/bin/mos wifi WIFI_NETWORK_NAME WIFI_PASSWORD

exit status 1
Command completed.

Does anyone have an idea what could cause this issue?

Thanks!

It looks like you ran

mos wifi

You have to run

mos wifi SSID PASSWORD

where SSID is the name of your wifi network and PASSWORD is its password.

Hi,

Thanks for the response.
I already tried with different wifi networks (SSID, PASSWORD).
But I receive always the same error response.

After a few additional attempts, I receive the following error message:

Looks like no flash space left on the device.
Check the free space. Run mos console and you should see something like this
