beacon advertise interval

[ziv123]

hello Nordic

i am working with nrf52832, sdk 6.0, softdevice s132 v7.0

i read around the forum that i can advertise a beacon packet every 20 ms 

but in the ble_app_beacon example the interval for the advertisement is written to be minimum 100ms ?? so where did that 20 ms go ?

however, since i don't know how to change the data of the message while advertising i put a timer handler that stops the advertise, update the data and start it again.

i put the timer to go every 50 ms and the advertisement interval every 50 ms i put a pin toggle every time i receive a ble from the address i am filtering..

1. the time is not fixed, maybe some messages are lost or maybe not sent, i don't know 

2. the intervals are larger then 50 ms .. more to the 100 ms  when they are sometimes fixed 

can you advice on this matter ?

i need to be sending changeable data in a beacon at list 30 times in one second

best regards

My apologies, I should have written out the entire function name - ble_advertising_advdata_update.

when writing this function in the app_ble_beacon example i get undefined reference error 

may be you know why ?

Please be specific about the error messages you are seeing. Is it an undefined reference error to ble_advertising.h?
In that case, you will need to make sure that you have included ble_advertising.h and the path /SDK/components/BLE/ble_advertising in your pre-processor defines.

If this is not the include error in question, please elaborate.

the argument of this function are unknown in the app_ble_example 10040, peripheral.

" unknown type name 'ble_advertising_t'; did you mean 'ble_version_t'? "

" implicit declaration of function 'ble_advertising_advdata_update' [-Wimplicit-function-declaration] "

Hi Ziv,

Again, the more specific and detailed your answers are, the easier it will be to help you resolve this issue.
From the two lines you included in your last comment, I would recommend that you check out your SES project settings, especially the preprocessor defines. Ensure that they include the path I gave you in my previous comment. Then, check that you have added the source file to your project files, and included the header file.

Looking forward to resolving this issue.

Best regards,
Karl

hi Karl

the path you mentioned is in the pre compiled file

i also copy the line cause i am not sure the pic is clear:

c_user_include_directories="../../../config;../../../../../../components;../../../../../../components/ble/ble_advertising;

so its not that or maybe it needs to be called from some other place ?

also added the following:

<file file_name="../../../../../../components/ble/ble_advertising.c" />

still same result 

best regards

Ziv
