SPP support with NimBLE (IDFGH-5581) #7303

Hi All, I wanted to know if SPP can be supported with NimBLE? Currently I am not using Bluedroid. I want to port SPP-Bluedroid to SPP-NimBLE. Is it technically possible and recommended? Does ESP have any plans to support SPP over NimBLE? Kindly help me with your suggestions on SPP feature with NimBLE.

Thanks, GR.Venkatesh

Hi @venkateshgr-ayla ,

SPP ( Serial Port profile ) is a basically a bluetooth classic profile. Nimble, is BLE only stack.

We can however achieve the same by implementing a custom LE service running on top of GATT and simulate the behaviour and achieve SPP functionality in BLE.

Currently, there is no such custom service implemented for Nimble. We will check internally and plan if we can release this as part of the SDK.

Thanks, Rahul
