flush out existing used pipe for reuse in nRF8001 in pic18f?

[gbiradar]

`Hi Guys, I have some sensor data of 20 bytes at each measurement at different period stored in EEPROM. Now i have to transmit all data over BLE continously.

example : say 20 bytes of data at 7 different time period = 140 bytes of data.

Now i'm using BlueSendData to transmit my data in while loop as i'm using pipe number 1 with buffersize of 20 bytes. what i'm seeing is that it is not updating my data measurement in android app. after some time i came to know that i have support of max. of 62 pipes with each pipe capability of handling 20 bytes of data.

what i'm looking is how can i flush out my pipe immediately after sending 20 bytes of data so that i can use same pipe for sending another 20 bytes of data.

regards, gbiradar `

The nRF8001 tells you when it is ready for more data with the DataCreditEvent.

See section 21.2, "Data command buffering" in the nRF8001 Product Specification.

I don't know whether it is correct or not, Once i send first 20 bytes of data i have read eventcode in while loop when eventcode returns data ack then i can send my next 20 bytes of data i checked with my application perfectly it is working.

What Awneil says is true: You have two available credits. So you can send one packet per event on average, or two in the same event if both buffers are prepared prior to the event. This means you have to check how many credits that are freed in the DataCreditEvent.

Hi run_ar, ok i understand what you said so here what i'm trying, I just want to test my nRF8001 working for over a undefined period continuously.It has to send one command and continuosly android app has to receive any kind of data for testing purpose. but i checked DataCreditEvent, it is part of Dataevents. i don't know how to implement it in my code i'm using a set of library which are for pic controller and i didn't find any library call with the name DataCreditEvent. If you have any link can you just send.

You can see an example how we do it in our library here.
