When E-1100A is on Power Status C or Power Status D, users could use pin7 RXD to wake up the UART
function. It will need some time to work normally after leaving low energy mode. In the process of
waking up the UART function, the AT command may not be recognized by E-1100A, so the data of
former bytes may be garbled. Users just need to send the commands again.
When E-1100A is on PWMODE =2 / 3 / 4, the status will be as follows after trigger by the RXD (pin7)：
PWMODE =2 : E-1100A will become PWMODE =1 from PWMODE =2.
Send PWMODE =2 commands again to get back to power saving status.
PWMODE =3 : E-1100A will become Power Status A. It will return to Power Status C if there's no any
communication on UART after 5 seconds.
PWMODE =4 : E-1100A will become Power Status A, but will still do BLE broadcast and sleep on
schedule as the setting. When it is on Power Status A, it will leave PWMODE=4 after
sending PWMODE=1.

Recommended soldering profile
Peak Temp245°C
Consider the "IPC-7530 Guidelines for temperature profiling for mass soldering (reflow and wave)
processes, published 2001.
Preheat phase
Initial heating of component leads and balls. Residual humidity will be dried out. Please note that
this preheat phase will not replace prior baking procedures.
◢ Temperature rise rate: max. 3 °C/s If the temperature rise is too rapid in the preheat phase it may
cause excessive slumping.
◢ Time: 60 - 120 s If the preheat is insufficient, rather large solder balls tend to be generated.
Conversely, if performed excessively, fine balls and large balls will be generated in clusters.
◢ End Temperature: 150 - 200 °C If the temperature is too low, non-melting tends to be caused in
areas containing large heat capacity.
Heating/ Reflow phase
The temperature rises above the liquidus temperature of 217°C. Avoid a sudden rise in temperature
as the slump of the paste could become worse.
◢ Limit time above 217 °C liquidus temperature: 40 - 60 s
◢ Peak reflow temperature: 245 °C
Cooling phase
A controlled cooling avoids negative metallurgical effects (solder becomes more brittle) of the
solder and possible mechanical tensions in the products. Controlled cooling helps to achieve bright
solder fillets with a good shape and low contact angle.
◢ Temperature fall rate: max 4 °C/s To avoid falling off, the REEZ E-1100A module should be placed
on the topside of the motherboard during soldering.
