3.8.6 NOTIF_IND notification Indication
i. Indication given by module.
ii. When the module receives data from the remote BLE device, it
notifies the user on UART.
iii. E.g. the command below shows some indication reports:
IND*:NOTIF_IND=1:0019 R_bytes:0014
dataFromBLEDev123456
IND*:NOTIF_IND=1:0019 R_bytes:0003
789
IND*:NOTIF_IND=1:0019 R_bytes:0014
abcdefghijklmnopqrst
IND*:NOTIF_IND=1:0019 R_bytes:0006
uvwxyz
IND*:NOTIF_IND=1:0019 R_bytes:0014
abcdefghijklmnopqrst
IND*:NOTIF_IND=1:0019 R_bytes:0006
uvwxyz
iv. In report “IND*:NOTIF_IND=1:0019 R_bytes:0014
dataFromBLEDev123456” the module shows CID as 1,
Characteristic from which data is received is 0x0019, the actual
received bytes are 0x0014, and then the actual bytes as
“dataFromBLEDev123456”.
v. The module can receive a maximum of 20 bytes i.e. 0x14 bytes in
one notification packet.
vi. If the remote device sends more than 20 bytes in one packet then
the module shows two notification indication messages. E.g. if the
remote device sends the string “dataFromBLEDev123456789”, the
module shows “dataFromBLEDev123456” first and then “789”.
