OK, the event ans SD call is part of the softdevice headers, so you shouldn't need the nrf_ble_gatt.h header. I.E the mtu request event is also handled by the GATT module (in nrf_ble_gatt_on_ble_evt)if you enable this in sdk_config.h. but it's fine to do that in main instead.

Actually, not. Although #include "nrf_ble_gatt.h was not mentioned direcgly in main.c, the nrf_ble_gatt.h header was already listed among others in Keil project pane. I believe, it's due to the fact that nrf_ble_gatt.h is cross-linked by other headers. But I still inserted #include "nrf_ble_gatt.h into main.c to be on the safe side.

Yes, it should. Did you actually need #include "nrf_ble_gatt.h for that to work?

It works! I just added: #include "nrf_ble_gatt.h" and

case BLE_GATTS_EVT_EXCHANGE_MTU_REQUEST:
			err_code=sd_ble_gatts_exchange_mtu_reply(p_ble_evt->evt.gatts_evt.conn_handle, 23);
			APP_ERROR_CHECK(err_code);
            break;

And also make sure that #define NRF_BLE_GATT_ENABLED 1 in sdk_config.h as well as configre NRF_BLE_GATT_BLE_OBSERVER_PRIO

@run_ar I'm using SDK14.2 As far as I undetstand, I should a) add #include nrf_ble_gatt.h b) add nrf_ble_gatt.c to sources c) add the code to ble_evt_handler();

@Toyman. Depends on which SDK you are using. Most likely the answer is yes, but you should check if you have the gatt module, nrf_ble_gatt.c. This module will handle the ATT mtu request.

@run_ar the combined ANT/BLE example doesn't have void on_ble_evt(ble_evt_t * p_ble_evt) function mentioned above. It has ble_evt_handler(ble_evt_t const * p_ble_evt, void * p_context)function. Is it where I should add the MTU handling code?

Thx. I'll try that. I'll also implement a longer workaround suggested in the link above. Will they work together?

RE: S332 BLE CONNECT IOS DEVICE

Most likely. If you do not handle that event today, that is the first thing you should fix.

I have exactly the same issue: I get "interrogation" failed in Lightblue, but Nordic apps do not work either. Does adding the event you mentioned solves the issue?

You must add event to void on_ble_evt(ble_evt_t * p_ble_evt) that is BLE_GATTS_EVT_EXCHANGE_MTU_REQUEST

@jwx555 which SDK version are you using? Please check if the solution found by @Tostikoning in the case he links to works for you.

Does the LightBlue app gives an error that the "interrogation" failed? Try the nRF Connect app. I am having the same issues with a only BLE application. See the following question devzone.nordicsemi.com/.../
