Hello,

Do you see this error every time? I just tried this out on latest code myself and I did not see this error (tried iOS as well as Android apps). The RainMaker app does not have the manual option for BLE provisioning, but can you try once with the "ESP BLE Prov" app?

Regards,

Hello and sorry for the delay. After updating iDF & RainMaker we get a different error.

NOTE: This only occurs with a specific chip. Others work fine.

***
On RM App we see: "Claiming finished with error: User does not have available quota. …"

We are inclined to toss this Dev Kit in the trash can and order some more dev kits

We are also happy to provide more detail and try "ESP BLE Prov" App. Would thisbe useful to you?

Best, George

Hi George,

All accounts have a default esp32 quota of 5. So, for the error "Claiming finished with error: User does not have available quota. …", you can just use a different account or send an email to esp-rainmaker-admin@espressif.com with some information of your requirements so that the quota can be increased.

Hello Piyush,

Thank you. However our ESPRainMake app (running on iPhone 2020) shows only 3 nodes (with 2 devices each). IOW, if we are consuming 5 RM nodes it is not obvious from RM app. Might this be associated with this other issue:

Deleting RM nodes from RM cloud: https://www.esp32.com/viewtopic.php?f=4 ... f8369410e1

TIA - George

Hi George,

The two are not related. The User-Node Association has no limit as such. As a user, you can add any number of nodes claimed by you, or someone else, or even self-claimed (for ESP32-S2). However, "claiming" has a different set of APIs and linking logic, which uses the ESP32's mac address as an identifier. It is possible that over a period of time, you may have claimed 5 different ESP32 nodes.

Regards,
Piyush
