Hello Arthur,
I have ported the simple serial socket client example code to CC1352P7 from your given link of github. All compilation errors are solved except some warnings.
I can see the uart terminal printing "Info: Done Initializing".
I have changed the required UUIDs as per required serial client code.
I am confused with how i can connect CC1352p7 with CC2650 (BLE peripheral) with manufacturer ID.
Please help me with this
Thank you,

Hello,
I have changed the code and now able to connect to the BLE peripheral CC2650.
static void SimpleSerialSocketClient_processAppMsg(ssscEvt_t *pMsg)
{
bool safeToDealloc = TRUE;
// Specify the address 84:C6:92:F3:E7:B0
// uint8_t targetAddress[B_ADDR_LEN] = {0x84, 0xC6, 0x92, 0xF3, 0xE7, 0xB0};//
uint8_t targetAddress[B_ADDR_LEN] = {0xB0, 0xE7, 0xF3, 0x92, 0xC6, 0x84};//
switch (pMsg->hdr.event)
{
case SSSC_EVT_ADV_REPORT:
{
target_addr_matched = 0;
GapScan_Evt_AdvRpt_t *pAdvRpt = (GapScan_Evt_AdvRpt_t*) (pMsg->pData);
// if (SimpleSerialSocketClient_findSerialStreamServer(
// SimpleStreamServerUUID, serverManufData,
// sizeof(serverManufData), pAdvRpt->pData, pAdvRpt->dataLen))
for (int i = 0; i < B_ADDR_LEN; ++i) {
if ((pAdvRpt->addr[i]) == (targetAddress[i])) {
target_addr_matched++;
}
else
{
unmatched++;
return;
}
}
if(target_addr_matched==B_ADDR_LEN)
{
// We found our device
scanningStarted = FALSE;
// Disable scanning
GapScan_disable("");
// Establish a connection to the device
GapInit_connect(pAdvRpt->addrType & MASK_ADDRTYPE_ID, pAdvRpt->addr,
INIT_PHY_1M, 0);
}
// Free report payload data
if (pAdvRpt->pData != NULL)
{
ICall_free(pAdvRpt->pData);
}
break;
}
i am checking the ble address of peripheral and if desired address device is found then connects to it.
for (int i = 0; i < B_ADDR_LEN; ++i) {
if ((pAdvRpt->addr[i]) == (targetAddress[i])) {
target_addr_matched++;
}
else
{
unmatched++;
return;
}
}
Now, I am getting this on Terminal,
but I dont see anything printed on terminal window when I type.
I think as per the readme on github, i need to enable the notification.
Please help me with this.
thank you,

Hi,
I found out that CC1352 is not able to discover the ble simple service on CC2650
I have changed the service uuid in simple_stream_profile_client.h and bcomdef.h as shown in attached image.
It is showing "SIMPLE_DISCOVERY_UNSUCCESSFUL"
Hi, (10 April 2024, 01:30 IST)
i think CC1352 is able to find the service UUID but some conditions in code are not met.
as per the screenshot,
in function uint32_t SimpleServiceDiscovery_discoverService(uint16_t connHandle, ICall_EntityID entity,
simpleService_t *service, gattMsgEvent_t *pMsg)
in Case,
case BLE_DISC_STATE_SVC:
{
// Service found, store handles
if (pMsg->method == ATT_FIND_BY_TYPE_VALUE_RSP &&
pMsg->msg.findByTypeValueRsp.numInfo > 0)
{
service->startHandle = ATT_ATTR_HANDLE(pMsg->msg.findByTypeValueRsp.pHandlesInfo, 0);
service->endHandle = ATT_GRP_END_HANDLE(pMsg->msg.findByTypeValueRsp.pHandlesInfo, 0);
// char * uart_msg_str = "Service found, store handles\n\r";
// UART2_write(uartHandle, uart_msg_str, strlen(uart_msg_str), NULL);
}
this "if" condition is not being satisfied.
and control directly try to exit the function with last line
return retVal;
Hi,
in my modified ported code, "Number of handles information" found is Zero,
and in the unmodified simple_central_LP_CC1352P7_4_tirtos7_ticlang code "Number of handles information" found is ONE,
Also I followed the instruction on https://software-dl.ti.com/lprf/simplelink_academy/modules/ble_01_basic/ble_01_basic.html and scanned for the attribute table of CC2650. Attching the screenshot for more inforamtion.
Hello Marie H,
Thank you for your help.
I have set the CC2650 to advertise on channel no 37 as per the instructions given in provided link and also verified that CC2650 uses channel no 37 to advertise it data using the sniffer.
Yes, sniffer by default uses the channel no. 37.
There is no change in the sniffer results.
I even tried to connect the CC2650 (BLE peripheral) with LightBlue android application and sent some data to CC2650.
But came to know that I don't get any sniffer information after both BLE central and peripheral gets connected to each other.
attaching the screenshot.
in screenshot after the connection, there is is no information about the BLE communication between this ble devices after connection is established.
I am sending a personal message containing the whole sniffer log for details.
May be the sniffer is not capturing the data after BLE connection is established.
(We have many ble devices (CC2650 and other) in office and I dont see none of them exchanging data on sniffer log, only ADV and SCAN RSP)
----------------------------------------------------------------------------------------------------------
Apart from this I wanted to share some information with you.
On the below link of github, there is a note about limitation of project.
It about different project CC2340R5 (SDK7.40). link given below,
But when i tried to co-relate it with my current problem and came to know about the initialized structure variable streamServiceHandle with .numChars = 2, in file simple_serial_socket_client.c (screenshot attached).
But in my BLE peripheral application it has 21 characteristics.
This structure is used in
Function uint32_t SimpleServiceDiscovery_discoverService(uint16_t connHandle, ICall_EntityID entity,
simpleService_t *service, gattMsgEvent_t *pMsg)
{
in file simple_service_discovery.c for service discovery related functions.
Does this has anything related to my problem?
thank you,

Hello Marie H,
I have update.
I took reference of Project "simple_central_LP_CC1352P7_4_tirtos7_ticlang".
and made some changes in simple_service_discovery.c file. (16 bit UUID is required instead of 128 bit)
As I changed service->uuid.uuid, to uuid and service->uuid.len to ATT_BT_UUID_SIZE.
I started to discover simple service successfully.
(Please refer the screenshot attached).
But still when I type something on console, i am not receiving anything on BLE peripheral side (CC2650)
regards,
Dnyaneshvar Salve
