uint16_t max_tx_octets:

/**< Maximum number of payload octets that a Controller supports for transmission of a single Link Layer Data Channel PDU. */

uint16_t max_rx_octets:

/**< Maximum number of payload octets that a Controller supports for reception of a single Link Layer Data Channel PDU. */

Hi Joakim

Thank you for your proposal... with this parameters it works fine.

Could you please explain me, what does achieve those parameters: dl_params.max_rx_octets and dl_params.max_tx_octets?

Hi Meriba!

Could you please try to add this code to the BLE_GAP_EVT_DATA_LENGTH_UPDATE_REQUEST in your ble_evt_handler():

dl_params.max_rx_octets = 0x64;
dl_params.max_tx_octets = 0x64;
dl_params.max_rx_time_us = BLE_GAP_DATA_LENGTH_AUTO;
dl_params.max_tx_time_us = BLE_GAP_DATA_LENGTH_AUTO;

Your code should now look something like this:

Hope that helps!
Best regards,
Joakim.

I'm using an Iphone 7 with iOS11.0.3, the same smartphone like in my test with the PCA10040, which will work fine.

That should be correct. What are you using to connect to your PCA10056 Board? If you are using a smartphone, which phone are you using?

I have uploaded the PCA10056 build from the project on a development board with nRF52840 in combination with the Softdevice S140 5.0.0-2.alpha.

I addition to superpak's comment; what softdevices are you using?

PCA10056 is for nRF52840 and PCA10040 is for nRF52832. Are you sure you are uploading it to the correct board?
