Serial Payload
PostPosted: Fri Apr 22, 2022 1:31 am     Reply with quote

Dear all, i would like to interface JDY-23 Bluetooth module to my Pic 18F4550 to transmit an receive data to Android mobile. Now to organize the transmission i would like to use one payload of data to every println. Is this possible please?

yes.
had a quick look at the datasheet and providing you're running the PIC at 3 volts, the interface is simple. I assume you're using a 'module' and not just the 'chip'....

Since it runs 'AT' commands, actual software should be easy to code and test as well.
You will of course have to use the HW UART of the 4550 and create an ISR with buffer. Look at EX_SISR.C as a basis for that.

Start with a simple test program, say to request and read the 'version' or 'ID' of the device. Once that works, ask for data from other 'registers', then set some registers data, read to confirm that data is correct. Add a couple LEDs and resistors, send the commands to turn them on/off. If these steps work, then you can write your 'real' program.
