Hi,
I am trying to implement LESC Security Mode 1 Level 4 with a peripheral ble_app_hrs on PCA10040 and a central via pc-ble-driver example heart_rate_collector_v6 with PCA10059.
I am following MSC Bonding: Passkey Entry: User Inputs on Central
My first step is to add sd_ble_gap_authenticate when BLE_GAP_EVT_CONNECTED comes. I have not yet implemented the full bonding sequences.
However, the call of sd_ble_gap_authenticate returns with 0x4
* @retval ::NRF_ERROR_NO_MEM The maximum number of authentication procedures that can run in parallel for the given role is reached.
I am running everything under Ubuntu 18.04.
Peripheral ble_app_hrs is modified based on nRF5_SDK_15.2.0_9412b96 with a little change:
