Stopping and starting wifi STA and AP modes programmatically

majorninth · June 27, 2019, 7:11pm

If you are asking a question, please follow this template:

My goal is: [describe your goal]
to be able to switch from ATS mode to AP mode and back again programmatically.
My actions are: [describe your actions - code, commands, etc]
Cfg.set(‘wifi.ap.enable’, true); // Enable AP mode
Cfg.set(‘wifi.sta.enable’, false); // Disable STA mode
let staDisconnect = ffi(‘bool mgos_wifi_dev_sta_disconnect(void)’);
staDisconnect();
The result I see is: [show the result - log, etc]
conf9.json saved
wifi is disconnected
then it starts back up again.
Note: connected and PUB/SUBing to AWS at the time.
My expectation & question is: [describe your expectation and your question]
I expect to be able to stop the STA mode and have AP mode enabled and running and also to be able to do the reverse.

I’m not sure your syntax is ok.

mongoose-os-libs/mjs/blob/63b401295ff3988e8367ddff6e513338bc9876c2/fs/api_config.js#L50-L62


// ## **`Cfg.set(obj, opt_save)`**
// Set the configuration. `obj` must be a subset of the whole configuation
// tree. `save` is boolean flag that indicating whether the change should
// be saved - it could be omitted, in which case it defaults to `true`.
// Examples:
// ```javascript
// load('api_config.js');
// Cfg.set({wifi: {ap: {enable: false}}});  // Disable WiFi AP mode
// Cfg.set({debug: {level: 3}});            // Set debug level to 3
// ```
set: function(obj, save) {
  return this._set(JSON.stringify(obj), save === undefined ? true : save);
},

var data = {
  config: {
    wifi: {
      sta: { enable: true, ssid: ssid, pass: pass},
      ap: { enable: false }
    }
  }
};
axios.post('/rpc/Config.Set', data).then(function(res) {
  return axios.post('/rpc/Config.Save', {reboot: true});
}).catch(function(err) {

You were right about the syntax…too much bouncing around between mos cmd line, MJS, JavaScript/HTML and C RPC calls, obj and JSON.

ended up with this in MJS:
Cfg.set({wifi: {ap: {enable: true}}}); // Enable WiFi AP mode
Cfg.set({wifi: {sta: {enable: false}}}); // Disable STA mode
Sys.reboot(0);
