Hi,
I'm using two nRF52832 (SDK14.2, SD132v5) to send data via Notify to one central. This central can be either a laptop or a smartphone.
The two nRF52832 has the same GATT Server configured but only the name of the peripheral change.
On my laptop there is no problem I can have both connected and received data from both.
But on Android (I don't have iOS to test), once I want to connect to the second board, the first one also receive a BLE_GATTS_EVT_EXCHANGE_MTU_REQUEST as if it was a first connection request. But since it is already connected, it crash. I'm having this issue even with the nRF Connect app.
I can't reproduce it on my laptop (macOS). When I initiate a connection to the second board, only this one receive the connection request.
