Hello. Interested to deploy the DA14531 certified BLE module inside an embedded design to access a local SPI device. Then perform some R/W with the SPI slave over a BLE enabled phone app.

For starters...

We have the following setup:

Using DA1458x Pro Motherboard with DA14531/DA14531 Module daughterboard

Configured jumpers as per Figure 11 on the website. No fly-wires.

Loaded up the CODELESS firmware onto the flash - actually have attempted

CODELESS DATA PUMP

CODELESS STANDALONE SET TWO HEX

with the same results.

Configured Teraterm to use our COM13 (on our setup) @ 57.6k.

Unable to send all the commands that are listed here:

http://lpccs-docs.dialog-semiconductor.com/UM-140-DA145x-CodeLess/atcomm...

The following are the results from the sent commands through Teraterm:

ATI
CodeLess DA14531 v_6.380.12.6
OK
ATZ

OK
AT+BDADDR
80:EA:CA:A0:08:8A,P
OK
AT+GAPSCAN

ERROR

According to the command list, should AT+GAPSCAN not work correctly? Why are we receiving an ERROR? Many of the command listed in the above table are also reporting similar ERRORs. Will keep reading for a resolution.

Thanks.
