Hi all! I know this module can be used as a ble beacon, has anyone have tried it?

all I can find is coded in arduino.

Use the forum Search function to look for NRF24L01 and you will find a lot of info including a CCS C driver in the Code Library

thanks for your reply, yes i have used this module a lot, but i need to know if anyone has used it as BLE beacon and how to configure it.

since you have ardunio C code, you can 'translate' it into CCS C code.

Google says 'beacon' is the BLE transmitting it's ID, say every second. If so seems easy enough to code. PIC reads BLE ID, then in 1HZ ISR, transmits that data ?

A beacon is a very simple device. All it is is a BLE device that broadcasts it's
ID at intervals.
Normally you would want to set the device to it's lowest power option,
and just send the ID at perhaps 2 second intervals. Nothing more.
There are other options and modes, but this would be the normal
approach for a device to trigger some action when a device looking
for the beacon gets close.
2 seconds was the standard for the original Apple protocol.
However beacons for other purposes may behave differently. So for
example, the AirTag does a much higher power broadcast, but only at
very long intervals (15 minutes!). Some like this look for a reply, and
then reduce their interval
The best settings, intervals etc., will depend on what the beacon is actually
for.
