Sleep Mode Power Too High - 14586 design migrated from da14583

Thu, 2019-09-12 03:38 -- sfullam

hi,

i ma moving a design from the da14583 to the da14586 and cannot achive the same sleep mode current measurements. i have the same PCB layout.

the design supports an LCD whose enable pin is set on Port 2_3, which is also used by as SPI_EN_GPIO_PORT by the SPI FLASH. In our 14583 chip when we are about to go to sleep then we set this Pin to Output low in order to turn off the power to the LCD and as a result our current consumption is 38uA in sleep mode.

SPI Flash power down current

We have an existing custom board that uses 14583. We have replaced the 14583 with the 14586 and all other circuitry is the same. The problem that we are having is that we are not able to reduce our current consumption to the values in the 14583

In our design we have an LCD whose enable pin is set on Port 2 Pin 3, which is also used by as SPI_EN_GPIO_PORT by the SPI FLASH. In our 14583 chip when we are about to go to sleep then set this Pin to Output low in order to turn off the power to the LCD and as a result our current consumption would be around 38uA in sleep mode.

maximum output power and antenna gain of ZOR 1.6mm antenna design from Dialog Semiconductor's application note AN-B-027

Can we please get the maximum output power and antenna gain of ZOR 1.6mm antenna design from Dialog Semiconductor's application note AN-B-027?

we used the ZOR 1.6mm antenna design from Dialog Semiconductor's application note AN-B-027 and included matching of the PCB trace for 50 ohms. During EMI/EMC testing, the test house is asking for a tune-up information which can be checked out maximum output power and antenna gain as in the example below:

Max output power:                                        5dBm

How to use the prod_test as DTM (Direct Test Mode)

Fri, 2019-09-06 15:15 -- anushiya

Hi,

I need the DTM for DA14586 and the instruction on how to use it. As a first step, before connecting a spectrum analyser, we want to make sure that the setup is correct. When a command is given from "prod_test_cmds" then the DA14586 running with the firmware "prod_test" return a response via UART.

We have compiled the 6.0.10.511\projects\target_apps\prod_test\prod_test for DA14586 and have downloaded to the internal flash of our custom board using JTAG. Our UART pins are p0_4 and p0_5. Now how can I use this to test on different modes?

Can The DA14586 be woken up in both Synchronously, via the BLE timer AND Asynchronously, via an external interrupt

Wed, 2019-08-14 08:00 -- anushiya

The DA14586 can be woken up in 2 ways: 1)  Synchronously, via the BLE timer which can be programmed to wake up the system, 2) Asynchronously, via an external interrupt (input). Can this be done at the same time.

That is: DA14586 is set as non_connectable device and set to broadcast in regular interval. It schedules the next advertising data update using 

app_adv_data_update_timer_used = app_easy_timer(APP_ADV_DATA_UPDATE_TO, adv_data_update_timer_cb);

Beacon mode of DA14586

Tue, 2019-08-13 21:51 -- karanshah28

Dear PM_Dialog,

I am developing one connectable beacon mode based demo using DA14586 micro controller. I have Dialog Pro kit and DA14586 module for development.

I have downloaded 6.0.10.511 SDK for DA14586 device. I am able to compile ble_all_in_one project code and able to flash it as debug mode using Keil and also able to discover DIALOG-ALL-IN device in BLE_SCANNER application.

Facing issue while generating combined binary using secondary bootloader and Firmware for DA14586

Sat, 2019-08-10 14:46 -- karanshah28

Dear Support Team,

I am using DA14586 EVM board to develop our project and looking for your help for below issue.

Issue:
I am trying to generate combine image i.e secondary bootloader + Firmware Image using project_multipart_binary_v2 python binary.
I am using DA14585_SDK_6.0.10.511_0 SDK for developemt.
