What softdevice so you use in your connectivity nRF52832 DK? Or What SDK version does that SoftDevice come from? S132v_X.Y.Z.

The debug stops at the function ble_opt_get, there is no going further as it is a softdevice function, I suggest you take a closer look to the code I've sent and maybe try to test it if possible so that you can tell me if you encounter the same problem, thanks

Can you try to step inside the function returning 0x3002? You can add "breakpoint()" in the project, which makes it possible to stop there with command line debugging.

Best regards,

That is exactly the problem. The softdevice returns the error 0x3002 as I mentioned above (isn't it a conn_handle error for the function ble_opt_get? Did I say something that confused you about the problem?

For some reason I thought the issue was that the function returned something saying that the conn_handle was invalid, but it isn't right? Is this a compiler error?

Here's how I implement the function and where the conn_handle comes from

self.conn_handle = conn_handle (during on_gap_evt_connected(…) function added in our program)

self.conn_handle = None (during on_gap_evt_disconnected (…) function added in our program)

Output debug on our program:

	Nom	Valeur	Type
◢	opt	<lib.pc_ble_driver_py.ble_driver.BLEOptGapChMap object at 0x00000000031D7D68>	BLEOptGapChMap
	◢ ch_map	[0, 0, 0, 0, 0]	list
	[0]	0x0	int
	[1]	0x0	int
	[2]	0x0	int
	[3]	0x0	int
	[4]	0x0	int
	conn_handle	0x0	int

Function in our program:

def GetChannelMapUpdate(self):

if(self.conn_handle == None):

opt = BLEOptGapChMap()

opt.conn_handle = self.conn_handle

opt.ch_map = [0x00, 0x00, 0x00, 0x00, 0x00]

self.driver.ble_opt_get(BLEOpt.gap_ch_map, opt)

New classes add in ble_driver.py:

class BLEOptGapChMap(object):

def __init__(self, conn_handle=1, ch_map=[0xFF, 0xFF, 0xFF, 0xFF, 0xFF]):

self.conn_handle = conn_handle

self.ch_map = ch_map

def to_c(self):

opt = driver.ble_opt_t()

opt.gap_opt.ch_map.conn_handle = self.conn_handle

ch_map_array = util.list_to_uint8_array(self.ch_map[::])

opt.gap_opt.ch_map.ch_map = ch_map_array.cast()

return opt

class BLEOpt(Enum):

common_pa_lna = driver.BLE_COMMON_OPT_PA_LNA

common_conn_evt_ext = driver.BLE_COMMON_OPT_CONN_EVT_EXT

gap_ch_map = driver.BLE_GAP_OPT_CH_MAP

gap_local_conn_latency = driver.BLE_GAP_OPT_LOCAL_CONN_LATENCY

gap_passkey = driver.BLE_GAP_OPT_PASSKEY

gap_scan_req_report = driver.BLE_GAP_OPT_SCAN_REQ_REPORT

gap_compat_mode_1 = driver.BLE_GAP_OPT_COMPAT_MODE_1

gap_auth_payload_timeout = driver.BLE_GAP_OPT_AUTH_PAYLOAD_TIMEOUT

gap_slave_latency_disable = driver.BLE_GAP_OPT_SLAVE_LATENCY_DISABLE

New function added in ble_driver.py:

def ble_opt_get(self, opt_id, opt):

err_code = driver.sd_ble_opt_get(

self.rpc_adapter, opt_id.value, opt.to_c()

)

return err_code

Can you show me the function where you call this? I need to know what context you use it in, and how you pass the connection handle into the function.

Best regards,

Edvin

No i can continue other tests that require the connexion and they work just fine (no disconnection event received either) I wonder if it is possible for you to test this with the library pc-ble-driver_py and see what you get as an answer.

RE: enable LE Ping with pc-driver-ble-py

Edvin — Tue, 17 Dec 2019 14:31:47 GMT

do you happen to get the disconnect event right after this call?

RE: enable LE Ping with pc-driver-ble-py

Imen — Tue, 17 Dec 2019 14:10:32 GMT

Yes I am using the variable holding the conn_handle value and i can see it in debug mode, the value is correct and of course I don't call the opt_get after a disconnection

RE: enable LE Ping with pc-driver-ble-py

Edvin — Tue, 17 Dec 2019 13:48:31 GMT

How do you pass the conn_handle into the opt_get()?

Are you sure you don't call this right after a disconnect? You should use the variable holding the conn_handle, to ensure that it is updated at all times.

Best regards,

Edvin

Hi thank you for your advice, I managed to do this. I would like to ask you now about the ble_opt_get, in fact, I want to perform an opt get on the channel map but it always return a conn_handle error (error 0x3002) and I don't understand why ( I am connected to only one device and the conn_handle value is 0) do you have any idea what to do? the opt_get works fine on a devkit peripheral but not on my tool using the pc-driver-ble-py library.

Hi,

Like you said, you are trying to add a function to pc-ble-driver-py that isn't already supported. I suggest you use the ble_cfg_set as a template and go from there, it has a similiar structur.
