Re: Disabling & Re-enabling BLE

Thanks for your reply... didn't really have anything in common as far as I could tell. I've got the functionality I need working now more or less, but I pretty much have to restart from scratch. It seems some things persist (GATT & GAP callbacks only need registering once at the start) but others do...

Disabling & Re-enabling BLE

I have an application which uses BLE and want to place the ESP into light sleep. I know it's not possible to maintain any BLE activity in light sleep mode, but should it be possible to disable bluetooth and re-enable the same configuration later, without having to re-initialise everything? Calling: ...

Dynamically registered gattc app makes esp_ble_gattc_open fail

I'm trying to make a program I've written support multiple client connections to different servers. I understand that each connection needs a separate app to be registered. My process is this: Perform a scan Application requests a connection to a certain BDA from the scan results BLE code creates a ...

Re: BLE Latency

As my original question stated:
Anyone have any idea what I could to minimise this latency (other than setting connection parameters)?
I'm looking for factors other than the connection parameters which may affect the latency, as I've already set these parameters to provide minimum latency.

BLE Latency

I'm working on a project which needs to send messages with the shortest latency possible. Each message is small enough to be sent in a single transmission, at the moment I'm just sending single bytes. I'm setting a GPIO pin on one board, sending using esp_ble_gattc_write_char and setting a correspon...
