nrf52810 not responding to SDK simple examples

You should be able to use any of the pca10040e examples, such as SDK\examples\ble_peripheral\ble_app_hrs\pca10040e.

As my colleage Bjørn says in this thread:

https://devzone.nordicsemi.com/f/nordic-q-a/29195/nrf52810-custom-board

You need to remove the preprocessor definition DEVELOP_IN_NRF52832 when you are actually running it on an nRF52810, and not simulating nRF52810 on the nRF52832.

In addition, make sure the NRF_SDH_CLOCK_LF_SRCm NRF_SDH_CLOCK_LF_SRC, NRF_SDH_CLOCK_LF_RC_CTIV, NRF_SDH_CLOCK_LF_RC_TEMP_CTIV, and NRF_SDH_CLOCK_LF_ACCURACY? are correct.

Also, make sure that the board file (you should change the preprocessor definition BOARD_PCA10040 to BOARD_CUSTOM, and create your own custom_board.h, which will replace pca10040.h. This new file should match the PCB that you are using. You can use pca10040.h as a reference.

Best regards,

Edvin

Sure, have found a module Nordic 52832 Chipset, and have alternate sources to use, meanwhile do you know any examples that you are familiar that will work with the nrf52810 chipset?

Sorry for being lengthy

On side too have no Laird SDK, which is not needed for this development yet, cause have only downloaded the examples from Nordic SDK web site,

for pointer 1, yes have done both with the prescribe with or without XTAL and change the clock settings, is in the video links, please refer to them again in the above, as right have tested adjusted the parameters, they are still responding the same as previous describe

pointer 2, this links shows, how it was flash, before and after editied the parameters/ add the XTAL is the same

Yes, have used 3 exmaples

this example, is the one that keeps the led on, which suggest that module is not yet configured?

3) is a modifed example from (2)direct_test_mode_pca10040e, have change it to the below image, toggle led on tx, rx pin 18, 19 to normal output generation, it seems not responding to the commands, instead only original direct_test_mode_pca10040e example have the led to light on, which even when and FTDI (USB - UART/TTL) device to the tx,rx pins, and connected comupter via a virtual terminal, there is no transmission

have debug using toggle led, yet the functions are not responding

I do not have a Laird DK, so I can not guarantee that any project that I compile works.

1. It looks like, from your "connections made" layout, that you are not using an LFXTAL. Please set this in your sdk_config.h file for your project:

#define NRF_SDH_CLOCK_LF_SRC 0
#define NRF_SDH_CLOCK_LF_RC_CTIV 16
#define NRF_SDH_CLOCK_LF_RC_TEMP_CTIV 2
#define NRF_SDH_CLOCK_LF_ACCURACY 1

After you have done this, please let me know what project you are testing on, and tell me the path to that sdk_config.h file.

2: How do you flash the application and the softdevice? Can you show me some screenshots?

3: Have you tried to debug? Is the main() function reached?

Yes have flash S112 device, and used the Nordic SDK, whereas the links send, therefore maybe could you have any simple example to share just to verify the modules bought are good? BLE651, nRF52810

Have not used Laird DK, this is to development quick models of the BLE transmission

RE: nrf52810 not responding to SDK simple examples

Edvin — Mon, 13 Jul 2020 08:42:03 GMT

But you flashed the S112 softdevice, then?

I don't know if the unmodified examples from the SDK will work. That depends on the pinout on your board. Check out the pca10040.h file in the SDK (or the equivalent file that is used in your project).

I am not familiar with Laird's evaluation boards. I suggest you contact them and check if they have any known issues or userguides.

Edvin

Laird provides an example from nRF52832 DK, instead of BLE 651 nRF52810, therefore did not flash S132 softdevice, all along have been using S112, pca10040e examples, yet the generic i/o commands to light up is not doing the command line given in the program, like previously explained?

RE: nrf52810 not responding to SDK simple examples

Edvin — Tue, 07 Jul 2020 16:36:07 GMT

Greetings,

The video containing the AT commands is not something that Nordic has made. The AT commands is preflashed software that Laird has made, so if you have questions for this, you need to discuss this with Laird.

Does Laird provide a separate board file that you are supposed to replace pca10040.h with? Because it doesn't have the same pinouts as the nRF52832 DK.

Did you remember to flash the S132 softdevice from SDK\components\softdevice\s132?

BR,

Edvin

Still not advertising, to detect the BLE651, Nordic UART , however when probe with the led using the example, shown in the image, is like the video mention, tx pin 19 lights up

#define DEVICE_NAME "Nordic_UART" /**< Name of device. Will be included in the advertising data. */

here's the video, from Laird, which i have connect using nrf connect application from the smartphone

Hello,

External LFXTALs are extremely sensitive, so attaching probes to them will make them not work. Please check the referance layout to see how much impendance they should have (the probes probably exceeds that by a lot).

I suggest you test this with the RC Oscillator first.

Try using an example from the ble_peripheral folder in the SDK, and open sdk_config.h and edit the following definitions:

#define NRF_SDH_CLOCK_LF_SRC 0
#define NRF_SDH_CLOCK_LF_RC_CTIV 16
#define NRF_SDH_CLOCK_LF_RC_TEMP_CTIV 2
#define NRF_SDH_CLOCK_LF_ACCURACY 1

Does it start advertising?

The extern OSC XTAL1, XTAL2, pin 24, 25 scope

seems not responding, not oscillating?

Have included the extern OSC, still the same for the example dtm as before the TX pin 19, always light up

yet the GPIO pin 19 led did not light up?

Here's the video link and the included images of extern OSC and LFCLK found locations

this link is the GPIO with extern OSC and the previous nrf_sdh.c have undo back to the softdevice previous configurations

From the data, there is a small terms and conditions for using the SDK example, on note, for the using the example of place an OSC, will do the following as well, check the config

NOTE 4

Not required for BL651 module normal operation. Nordic SDK examples by default assume that the external 32.768kHz crystal is connected. You mustmodify the Nordic SDK example to reflect if the external 32.768kHz crystalis fitted or not.The on-chip 32.768kHz RC oscillator provides the standard accuracy of ±500 ppm, with calibration required at least every eight seconds to stay within ±500 ppm.BL651 also allows the option ofconnectingan external higher accuracy (±20 ppm) 32.768 kHzcrystal to the BL651pins SIO_01/XL2 (pin 24) and SIO_00/XL1 (pin 25). This provides higher accuracy protocol timing and helps with radio power consumption in the SYSTEM ON IDLE or SYSTEM OFF modes by reducing the time that the Rx window must be open.

Please allow me to test it out for a moment, while i get back to you

In the meantime, here's to reply your curioisity

Yes, in the beginning was using the example to do UART communication from SDK

Next the hardware, yes am using internal RC OSC,

"How this is done depends on whether you use the softdevice or not." quoting from you

actually does softdevice or not, still the OSC requires to be configure, cause the enable single GPIO is also not responding the video using the dtm example (direct to mode, althought this is in UART)

as have bought the module without the development kit, to development a package, later on there will be more queries on how to scan via pairing dongle

Hello,

Does your application use the softdevice?

From your HW diagrams it looks like your HW doesn't have an LFXTAL, is that correct? If so, you must configure your device to use the internal RC Oscillator. How this is done depends on whether you use the softdevice or not.

Search for LFCLK in sdk_config.h

Edvin
