How to receive ble data when esp32 used as master?

[xzwang]

I want to receive data from slaver(nrf51822), Master is ESP32. Connection has established between ESP32 and nrf51822.
Master(ESP32) <------- Connection Established--------->Slaver(nrf51822)

ESP32 sent an request and nrf has responsed, but I have no idea how to receive the response.

Anyone can help me? Thanks.

I too am learning BLE APIs on ESP32 as fast as I can ... would you be able to post an attachment with the code you have so far ... I'll be happy to partner with you so we can both learn.

I have fixed this issue, the event ESP_GATTC_NOTIFY_EVT will come when received a notify. I didn't call esp_ble_gattc_register_for_notify when recvived characteristic that its property was 0x10. It is the key reason.

Anyway, Thanks.
