CC2640: OAD with Android App issue : Device Disconnects Randomly

Other Parts Discussed in Thread: CC2650

Hi,

We're trying to write an Android App to on-chip OAD into a CC2640 custom board. We have already tested the OAD using BTool + CC2650_USB_Dongle. It works perfectly fine.

We've followed all the steps mentioned in CC2640_OAD_Guide and came across an issue that Device gets disconnected in the middle randomly while OAD.. We're still not sure but based on our previous experience this issue might be due to incorrect connection parameters (CONN INTERVAL).

Following are the connection parameters that we're currently using:

/*********************************************************************
 * CONSTANTS
 */
// Advertising interval when device is discoverable (units of 625us, 160=100ms)
#define DEFAULT_ADVERTISING_INTERVAL          80

// Limited discoverable mode advertises for 30.72s, and then stops
// General discoverable mode advertises indefinitely
#define DEFAULT_DISCOVERABLE_MODE             GAP_ADTYPE_FLAGS_GENERAL

// Minimum connection interval (units of 1.25ms, 80=100ms) if automatic
// parameter update request is enabled
#define DEFAULT_DESIRED_MIN_CONN_INTERVAL     1024

// Maximum connection interval (units of 1.25ms, 800=1000ms) if automatic
// parameter update request is enabled
#define DEFAULT_DESIRED_MAX_CONN_INTERVAL     2048

// Slave latency to use if automatic parameter update request is enabled
#define DEFAULT_DESIRED_SLAVE_LATENCY         0

// Supervision timeout value (units of 10ms, 1000=10s) if automatic parameter
// update request is enabled
#define DEFAULT_DESIRED_CONN_TIMEOUT          100

// Whether to enable automatic parameter update request when a connection is
// formed
#define DEFAULT_ENABLE_UPDATE_REQUEST         GAPROLE_LINK_PARAM_UPDATE_INITIATE_APP_PARAMS

// Connection Pause Peripheral time value (in seconds)
#define DEFAULT_CONN_PAUSE_PERIPHERAL         1

// How often to perform periodic event (in msec)
#define OTA_PERIODIC_EVT_PERIOD               20

// The size of an OAD packet.
#define OAD_PACKET_SIZE                       ((OAD_BLOCK_SIZE) + 2)

// Task configuration
#define OTA_TASK_PRIORITY                     1

#ifndef OTA_TASK_STACK_SIZE
#define OTA_TASK_STACK_SIZE                   644
#endif

// Internal Events for RTOS application
#define OAD_STATE_CHANGE_EVT                  0x0001

Android logcat output for the failed OAD attempts are as follows:

Packet Sniffer data while one of these attempts is in the following file:

0844.OAD_Snif.psd

Also, we have found, cloned and built this repo suggested in one of the e2e threads:

But, this seems to be for Off-Chip OAD process. Please suggest any on-chip OAD example, if there is any..

Thanks!

    Hi Sharath,

    When I look at the sniffer log it seems like it's the phone that stops sending new data over the air.

    Admittedly, at some point later it looks like the slave has decided to not be in the connection any more, but for a good while they are both online and the phone does nothing after receiving the notification about which OAD block number is expected next. Can you comment on that?

    Also, it looks like your connection interval is almost a second after the update request from the slave. That seems a bit excessive and the OAD process will take forever. 20-100ms would be faster (obviously) but still slow enough that the slave has plenty of time to write the received data to flash.

    Best regards,
    Aslak
