i can't connect to my device sd_ble_gatts_exchange_mtu_reply error 8

[vea45]

Hi,

I have an nrf52 with sd 132 3.0.0 and SDK 12.2 which after turning it on I can connect to it without problems, but after some time (maybe 10-15 minutes) I can't connect to it again the connection drops before it can be established. I'm debugging the board and I get an error 8 at this function "sd_ble_gatts_exchange_mtu_reply" when the BLE_GATTS_EVT_EXCHANGE_MTU_REQUEST is called during the connection...

Any ideas?

I discovered that the device was disconnecting before the connection was established due a timer that was triggering inmediately. This timer (in my application) was a connection timeout timer. I applied this solution to the timer library: devzone.nordicsemi.com/.../

And now it works, thank you!
