ble_gatts_evt_write_t Length is 0

[David]

Hello,

I am running an older softdevice 4.0.2

And  finding that occasionally the len field is returning 0 when receiving a  ble_gatts_evt_write_t ble event in my Peripheral device.

Is there any reason for this? There is data inside the data[] array this is problematic however because i am using the len field to determine how many bytes should be written over UART.

Regards,

Hi,

Are you sure that this is a BLE_GATTS_EVT_WRITE  event ? Could you post some code that shows how you handle the event and how you print the value of the len field?

Also, what is the value of ble_gatts_evt_write_t::op when this happens ?
