I am struggling to understand how to use a Soft Device 132 on a BT832 fanstel part. I need to have the uart come out on pin 1 and 2, and have hardware handshaking enabled. I cannot find which I/I pins are available under the softdevice 132. The desired configuration is a hardware controlled uart, with a connect signal on an I/O pin, a Sleep status signal on an I/O pin, a DATA/CMD input pin that will put the device into command mode for AT commands, and data pass through mode, and a DATA ready output pin. In this configuration, I believe I can replace the RN4020 module that we used in a prior failed product. The fanstel firmware has no source, and no documentation. They have hex file BT832_AT_3in1PC18113.hex which says it has soft device 1320v6.6.6 +BT832_AT_UART without 32k buffer+bootloader. But no information on how one could use it. Ultimately, the goal is to have code running on the BT832, that controls another device, with a serial port, and I/O lines.
What pins are available on the SD132 when using a 52832 device?
How do you configure them?
How can you add custom code to the soft device? Is there a tutorial somewhere?
And how do I do a soft reset?
How do I manage to reconfigure the code so that the uart is mapped to two of the castellated pins (1 and 2) and that the uart has hardware flow control brought out to a pair of pins on the castellated package.
The BT832 castellated pinout 1= SDA 2=SCL 3-4 xtl 5 =P002, 6= P003 7=NFC1 8=NFC2 11=P013 12= P018 13=P020 14=P021 15=SWCLK 16=SWDIO.
