whenever call ble_db_discovery_start().

call memset(&m_ble_db_discovery,0,sizeof(m_ble_db_discovery)); before ble_db_discovery_start()

I don't understand it either. The line should be moved before the if, so from 229 to 224.

Hi, I do try the memset(&m_ble_db_discovery,0,sizeof(m_ble_db_discovery)); before ble_db_discovery_start() and it work fine. I try many time like below: scan my target -> connect target -> disconnect target -> reconnect but I dont understand another suggestion about "In ble_db_discovery.c move p_db_discovery->curr_char_ind = 0; from line 237 to line 234."

If each device I only discovery main service what should I do about p_db_discovery->curr_char_ind = 0; Keep that is 0 or just mask this line.

Thanks

Ok, but have you tried to use the debugger to see what is happening inside the module? It could also be that you are hitting this bug, you could try the fix.

I use PCA10040 EVB and I also enable nrf_log so after first time I connect to 4 devices and disconnect those devices. I do connect again the UART port log just stop like below:

BLE_DB_DISC:INFO:Starting discovery of service with UUID 0x180d for Connection handle 1
BLE_DB_DISC:INFO:Service UUID 0x180d Not found
BLE_DB_DISC:INFO:Starting discovery of service with UUID 0x1816 for Connection handle 1
BLE_DB_DISC:INFO:Found service UUID 0x1816
BLE_DB_DISC:INFO:Discovery of service with UUID 0x1816 completed with success for Connection handle 1

and no more connect action. If I press reset button then connect is fine but reconnect will stop like that.

Thanks

With regards to the SoftDevice you don't need to do anything else. What do you mean by stuck? Is ble_db_discovery_start() returning an error? If not, where is it "stuck"?
