[GitHub] [mynewt-nimble] freeride01 opened a new issue #1193: Passkey/password pairing with NimBLE?
freeride01 opened a new issue #1193:
URL: https://github.com/apache/mynewt-nimble/issues/1193
Hello,
I have the following question. I have a BLE device based on ESP32. It does not have input or output capabilities. I am using ESP-IDF and the NimBLE stack, which I'm very pleased with so far.
I want to do password authentication as follows:
1. User pairs to the ESP32 device from a smartphone app.
2. User generates a passkey or password and sends it to the ESP32 device, which in turn sets it as a password for pairing.
3. The next time a user wants to connect, the ESP32 device sends him a request for password.
4. If he enters the correct password, he pairs to the device. If not, he cannot pair.
Is this possible with the NimBLE stack and is there example code for this scenario?
Thank you in advance.
P.S. obviously I read the part about security in BLE user guide ([https://mynewt.apache.org/latest/network/ble_sec.html](url)), but there were no examples on exactly how to implement passkey pairing.

yes, no input/no output iocapa doesn't allow for authenticated pairing

As far as I can see, when you have a "no input/no output" device (as I do), you can't set a passkey.

No replies, so I guess this is not possible.
In that case, has anyone had any success in modifying the BLE peripheral API to include a password for pairing?

So is there a way to temporarily disable all gatt services/characteristics except one (for the password) and when the user enters it, they are enabled again?

Hi,
You can check btshell, it implements all pairing models

Let me rephrase the question: in the project I am using for a template, the GATT server is started with `gatt_svr_init()`.
1. How do I stop it during runtime, since I can't find a `gatt_svr_deinit()` function?
2. Can I initialize GATT with a custom array of services, something like `ble_gatts_add_svcs(my_custom_array)`?
