Hi all
I have an issue regarding central- peripheral connection.( using nRF52832)
In the past I developed a peripheral device using SDK 11.
In order to manufacture it- I’ve also developed a “tester” using a ble_central example.
The tester’s job was to:
Search the tested peripheral advertisement , connect to it(+PASSKEY),
read & write a characteristics.( read & write: to test some peripheral HW)
All was working fine, till the SDK11 peripheral doesn’t work properly with new cellphones .
So I’ve redeveloped the peripheral using SDK17
Trying to connect SDK11 central to SDK17 peripheral results:
Central searches & finds the peripheral, connecting to it (if 1st time- then requesting the PASSKEY) .
reading from a characteristic results in data length =0 .
So I rewrote the central (SDK17) ,starting with ..\examples\\ble_central\ble_app_hrs_c .
As of now : the central searches & finds the peripheral.
Then I use sd_ble_gap_connect to try to connect.
I have a LED in the peripheral
It goes on in ble_evt_handler() if p_ble_evt->header.evt_id== BLE_GAP_EVT_CONNECTED
Goes off if == BLE_GAP_EVT_DISCONNECTED
According to that LED- a connection for a very short time is made, than disconnects.
The peripheral has a PASSKEY but nowhere in the central does anyone requests it:
That is: never (p_ble_evt->header.evt_id)== BLE_GAP_EVT_AUTH_KEY_REQUEST
So I never get the chance to use sd_ble_gap_auth_key_reply to set a PASSKEY
It seems that the problem is before the PASSKEY
What needs to be done?
Thanks
Yona
