Hi,

So how do you fix this problem?
we face the same problem in some android phone while others work fine.
Any tips would be appreciated.

Thank you very much for your replay. Seems like I mixed up HEX 0x13 and DEC 19. Makes much more sense now!

Hi,

If you are getting NRF_ERROR_RESOURCES (0x13 = 19) when calling sd_ble_gatts_hvx() that is pretty normal, and means that the softdevice buffer is full. You need to try again when some data is sent (typically after BLE_GATTS_EVT_HVN_TX_COMPLETE occurs). You should look into how you handle the NRF_ERROR_RESOURCES error code, for instance you don't need to assert.

Best regards,
Kenneth

Sorry I wrote down wrong connection parameters. I´m actually using the following connection intervals:

// in main.c
#define MIN_CONN_INTERVAL               MSEC_TO_UNITS(7.5, UNIT_1_25_MS)             /**< Minimum acceptable connection interval (20 ms), Connection interval uses 1.25 ms units. */
#define MAX_CONN_INTERVAL               MSEC_TO_UNITS(400, UNIT_1_25_MS)             /**< Maximum acceptable connection interval (75 ms), Connection interval uses 1.25 ms units. */
