i. Execution only command
ii. When the Characteristic Value is longer than can be sent in a
single Read Response message, user can use this command to
read that value in one command.
iii. Read data from BLE device for the characteristic which has
properties as “Rd” i.e. 0x02.
iv. Command format is “AT*RdLongChar=conn-ID, char-Handle”.
v. Commands which support “rdcharval” can also be read by this
command.
vi. Response to the command shows bytes received, offset of current
data with respect to the whole data, and MoreToCome (MTC) flag
if there is next data packet expected on the same characteristic
read.
vii. Refer following read examples for more detail.
