I'm using a mostly un modified 'gatt_security_server'.
I added a print on reboot to show bonded devices.
This particular example does not seem to be seeing ESP_GAP_BLE_AUTH_CMPL_EVT when I connect using the nordic nRF connect utility from my phone. Oddly, I can write to UUID 1A37 after the key exchange. I've highlit that in the code below.
I have my own application based on a BLE HID example that is seeing ESP_GAP_BLE_AUTH_CMPL_EVT, but the bonding/pairing information does not seem to persist in either project.
My goal is to pair/bond a device, and
- disconnect/reconnect from the host/central without pairing again
- allow the device to reboot, and allow the host/central to connect without pairing again
- allow the device to power cycle, and allow the host/central to connect without pairing again
Other than the gatt secure server walk through, are there some docs that I'm missing related to this?
Where is the whitelist documented? Should I be using that?
I have no IOCAP - no display, no input.
I've tried ESP_LE_AUTH_BOND, and ESP_LE_AUTH_REQ_SC_BOND with different failures on reconnect
Here are some logs of what I'm seeing
