Maximum throughput while using DA14580 over external SPI

Tue, 2020-07-14 20:12 -- tsgowtham

Hi,

I have a custom board where the DA14580 is used as a secondary/slave MCU with another primary MCU. I would like to know as to what maximum throughput can be hit while using a payload of the default 20 bytes before SPI or any other factor becomes a bottleneck. Are there any official figures or any testing done for this?

Thanks

Receiving CUSTS1_VAL_IND_CFM instead of CUSTS1_VAL_NTF_CFM in prox_reporter_ext

Hi,

I have a modified version of prox_reporter_ext where I have 3 characteristics with notification configured for all. When I use the LightBlue app for android to subscribe to notifications of a specific characteristic, I received CUSTS1_VAL_IND_CFM (0xDC08) instead of CUSTS1_VAL_NTF_CFM .

 

Below is the configuration of the characteristic to which I tried to subscribe:

Reply not received while sending a create_db message in the empty_template_ext project

Thu, 2020-06-11 09:21 -- tsgowtham

Hi,

I am trying to modify the empty_template_ext project to use the cust1 profile. I added my characteristics details in the user_custs1_def.h/.c files and included "custs1.h" in user_profiles_config.h

When I send the message to create the cust1 DB, I do not receive any reply. I've attached a screenshot of the messages sent and received from the host(which is a modified version of the host_proxr project).

I've tested the working of the characteristics by modifying the prox_reporter_ext project and this had worked as expected. 

 

Issues with using JLink on custom DA14580 board

Wed, 2020-06-03 12:49 -- tsgowtham

Hi,

I have 2 custom DA14580 boards and am facing an issue while trying to debug with Keil. When I go to the debug settings and press scan, initially it detecct to show the cortex m0. But then after few seconds it would not detect it. Currently, it's unable to detect the m0 even for a short duration. 

The debugger gives 2.8V at the DA14580's VBAT. 

Any methods on how I could debug this issue or what could cause this?

Thanks

Enabling CFG_TRNG error

Thu, 2019-05-09 16:26 -- dlo

I would like to enable the True Random Number Generator to create advertising intervals to prevent collision among several units.

I'm editing the DA1458x_beacon_v_5.40.2 project files.

In DA1458x_config_advanced.h I define:

#define CFG_TRNG 

Using Keil uVision v5.27.1.0 I click rebuild all target files. I then end up with this error:

.\out_580\dialog_beacon_580.axf: Error: L6218E: Undefined symbol trng_acquire (referred from arch_system.o).

At first the trng.h file gave me an error: error: unknown type name 'uint8_t'

indicate下怎么发送数据

Wed, 2019-03-06 06:35 -- kongxiangmin

Hi,Dialog,
在原来的DSPS例程中,使用的是notify,用user_send_ble_data()就可以发送数据,我将notify更改为indicate以后,再使用user_send_ble_data()就不能发送数据了,是否需要使用别的函数在indicate下发送数据?
