ble_gatts_evt_write_t questions

[Mohamed O.Abouzeid]

I have some questions about how I will use this structure ,first of all I know that The "data" member of the ble_gatts_evt_write_t is meant as a placeholder for the address in memory where the array containing the data received over the air lives. This means that, without modifying the header file, you can simply get the data by accessing:ble_gatts_evt_write_t::data[0 .. len-1] So assuming that ble_gatts_evt_write_t::len was 10, you could access: ble_gatts_evt_write_t::data[0] .. ble_gatts_evt_write_t::data[9]

I have two somethings that confused me: what will happen if I didn't send packets for a while and the chip didn't sleep then I send again packets will it write starting from data[0] or will complete on the array?

the same case but the chip in this case go to sleep and then I started to send again.

I'm also asking about how to make the chip to erase the array of the data received from air every time it start receiving packets from air?

Your question is very hard to understand. And I don't know what 'Alex Lynchosky' means.

Every time you get the BLE_GATTS_EVT_WRITE the included ble_gatts_evt_write_t structure is valid for that one single event, the data buffer is exactly the data for that event, as soon as you've finished processing it and returned, that's the end of the buffer.

I'm sorry for making you confused but thank you I got it :) :)
