I have to delay 10ms between notifications.So the speed is about 2KB/s.

<help>Ble app reg failed:BTA_GATT_NO_RESOURCE

Hi

In BLE ,6 services works well.
But 7 services reports error:BTA_GATT_NO_RESOURCE.

So, the number of service in Ble is limited to 6.
Is that true?
or this is just for ESP32?

thanks!
