Example of AT Command set for BLE
The aim of this archive is to show an example of AT Command set for BLE. The project currently supports ISP1507-AX, ISP1907-LL, ISP1907-HT and ISP1807-LR modules. Visit https://www.insightsip.com/products/short-range-modules to know more about these modules.
An application note is available at:

The examples are ready to use with the Segger Embedded Studio (SES) IDE.
SES provide a free license for development on nRF devices. Licenses can be requested at https://license.segger.com/Nordic.cgi

The following modules are supported:
| Module | Softdevice | RX pin | TX pin | CTS pin | RTS pin | SEL pin |
|---|---|---|---|---|---|---|
| ISP1907-LL | S112 | P0.08 | P0.17 | P0.03 | P0.05 | P0.11 |
| ISP1507-AX | S132 | P0.08 | P0.06 | P0.07 | P0.05 | P0.04 |
| ISP1807-LR | S140 | P0.08 | P0.06 | P0.07 | P0.05 | P0.04 |
| ISP1907-HT | S140 | P0.08 | P0.06 | P0.07 | P0.05 | P0.04 |
AT+BLEPHY? and AT+BLECONNPARAM? return startup values cannot be trusted.
This is due to the fact these parameters have to be negotiated each time a new BLE connection is established.
When a connection is establish the host needs to manually call AT+BLEPHY and AT+BLECONNPARAM to set these parameters then it can check the result with AT+BLEPHY? and AT+BLECONNPARAM?
