Error 3 Write Not Permitted

[tkrmnz]

Revisiting the write notify project from my previous issue request. I'm getting an "Error 3 Write Not Permitted" error. Same as before, the notify can be triggered via CYSmart app on windows and Android BLE serial terminal. I'm running V18 of btlib.c.

Here is the devices.txt DEVICE=BLE device TYPE=LE NODE=2 ADDRESS=60:B6:47:62:59:8A LECHAR=Data HANDLE=001D PERMIT=14 SIZE=60 UUID=FEC26EC46D7144429F8155BC21D658D6 ; index 0
LECHAR=CCC1 HANDLE=001E PERMIT=08 SIZE=2 UUID=2902 ; index 1

Here is the LE_Client.c

include

include "btlib.h"

int notify_callback(int lenode,int cticn,unsigned char *buf,int nread); int main() {

unsigned char data[8]; data[0] = 0x01; data[1] = 0x00;
if(init_blue("devices.txt") == 0) return(0);

connect_node(2,CHANNEL_LE,0);

//write_ctic(2,1,data,0); notify_ctic(2,0,NOTIFY_ENABLE,notify_callback);

// read notifications for 1 minute

read_notify(10000); output_file("monitor2.txt");

disconnect_node(30); close_all(); return(0); }

int notify_callback(int lenode,int cticn,unsigned char *buf,int nread) { // LE device lenode has sent notification of characteristic index cticn // data in buf[0] to buf[nread-1]

printf("Notify %02X %02X %02X\n",buf[0],buf[1],buf[2]);

return(0); }

Monitor.txt output

This local device has been allocated NODE = 1000 It should be added to the devices.txt file as follows: DEVICE=name (e.g. My Pi) TYPE=MESH NODE=choose (e.g. 1) ADDRESS=DC:A6:32:0C:FC:BC Connect OK as LE client Error 3 Write Not Permitted

Error 3 is returned by the Bluetooth adapter, it is not a btlib-generated error. Now that btlib has been fixed to send a write with acknowledge read, it is not necessary to include the notify UUID 2902 in devices.txt. So first thing to try is delete the LECHAR=CCC1 entry.

I found the issue, HANDLE went from 001D to 001B. I also removed the CCC1 entry in the Devices.txt. Again, thank you for your assistance.
