How to change the wifi AP credentials on an existing (claimed) node?

[hamishcunningham]

Hello! Rainmaker looks great, thanks!

One question: I've moved a device to a different location and need to give it new wifi credentials... is there a way to do that without erasing flash and creating a new device?

I tried

Code: Select all

$ ./rainmaker.py provision ...node id...

but I get:

Please connect to the wifi PROV_XXXXXX and Press Enter to continue...

(and no AP appears that I can join).

Hi Hamish,

If you are using any existing examples, pressing and holding the boot button for more than 3 seconds and then releasing it will reset the Wi-Fi credentials. You can then re-provision from the phone app.

Provisioning from CLI would work for SoftAP provisioning, but the default for ESP32 is BLE provisioning, so you won't find the network PROV_xxxxxx. The reason why CLI has SoftAP provisioning is that we had initially launched ESP RainMaker for ESP32-S2 only, which does not have BLE.

Hi ESP_Piyush,

I'm looking for an example of how to press and hold the boot button for more than 3 seconds and then release it to perform a specific action. I attempted to use a Semaphore Binary, but occasionally, the interrupt seems to trigger automatically. I think that incorporating a timer for the button holding might resolve this issue.

Any help would be appreciated.

You can check the app_reset component of esp-rainmaker/examples/common which is used in all the RainMaker examples.
