plt_fw wo uart

Sorry, for the confusion.

What i want to say is that i don't have physical acces to the uart ports or any other pins on my final product.

The only interface i can use on my product is a push button. Thus i'd like have the plt firmware start to transmit unmodulated data at boot and then eventually swich the frequency of the unmodulated tx by using the button.

With that in mind i added a small function to dglt source code but with no success,

void hci_unmodulated_tx(uint8_t freq)
{

uint16_t Opcode=0x83FC;
uint8_t param[2] = {0x54,0};

param[1] = freq;

uint8_t cmd_data[6]={0x01,0x83,0xFC,0x02, 0x54,freq};
size_t param_len=2;//sizeof(param);

OS_ASSERT(uart.msg == NULL);

/ / uart。味精= dgtl_msg_alloc(DGTL_PKT_TYPE_HCI_CMD, sizeof(dgtl_pkt_hci_cmd_t) + param_len);
// memcpy(uart.msg->data, cmd_data, sizeof(cmd_data));
dgtl_msg_prepare_hci_cmd(uart.msg,Opcode,param_len,¶m);

push_frame_to_queue();
// uart_start_packet();
//for debug on prodk
ad_uart_write_async(uart.dev,uart.msg->data,sizeof(dgtl_pkt_hci_cmd_t) + param_len,uart_tx_done, NULL);
}

I am debugging this on pro dk for now.

Thanks

Hi dialog,

on prodk, i still need to send command through uart in order to set the chip in unmodulated tx,

When i am trying to push command in the dgtl queue without using uart, a hard fault occurs.

I am trying to debug what is going on but the plt fw is quite complicated to understand.

Is there any way to set fw in unmodulated tx by default at start up.

Dear Dialog,

I found a "dirty" solution that fix my problem for now.

I directly set the cmd i want in the ble_mgr_task :

SE_DGTL
if (ulNotifiedValue & mainBIT_DGTL) {
dgtl_msg_t *dgtl_msg;

// dgtl_msg = dgtl_receive(DGTL_QUEUE_HCI);
uint16_t Opcode=0xFC83;
uint8_t param[2] = {0x54,0x13};

/ / uart。味精= dgtl_msg_alloc(uart.frame_header.pkt_type, header_len + param_len);
dgtl_msg = dgtl_msg_alloc(DGTL_PKT_TYPE_HCI_CMD, sizeof(dgtl_pkt_hci_cmd_t) + 2);
dgtl_msg_prepare_hci_cmd(dgtl_msg,Opcode,2,¶m);

and then notify the task once the system init is done.

I can manage certification like this.

Thanks for the help
