Page 12: Reset
BlueMod+S/AI Hardware Reference 3.3 Reset BlueMod+S are equipped with circuitry for generating power-up reset from the supply voltage VSUP, as well as brownout detection. During power-up, reset is kept until the supply voltage VSUP has reached the minimal operating voltage. VSUP risetime has to comply with Table 1 for power-up reset to function properly. A reset is also generated when VSUP falls below the threshold of the brownout detector (1,6V .. -

Page 19: Slow Clock Interface
BlueMod+S/AI Hardware Reference 3.9 Slow Clock Interface Even though an external slow clock is not required for BLE operation, consumption of power during power-down modes can be reduced by feeding the module with an optional 32,768 kHz slow clock at pin XL-IN/SLCK, or connecting an XTAL (32,768kHz) and two capacitors C1, C2 at pins XL-IN and XL-OUT. -

The crystal has to comply with specifications given in Table 1. The exact value of C1 and C2 depends on the crystal and the stray capacitance of the layout. -
Page 21: Operating In A Power-Switched Environment
BlueMod+S/AI 3.11 Operating in a Power-Switched Environment A potential "back feeding" problem may arise, if the module is operated in an environment where its power supply (VSUP) is switched off by the application. This might be done to save some power in times Bluetooth is not needed. -

Page 37: Placement Recommendation
To achieve best radio performance for BlueMod+S/AI, it is recommended to use the placement shown in Figure 17. This is a “corner placement” meaning the BlueMod+S/AI is placed such that the antenna comes close to the corner of the application PCB (red area). So, the yellow area is outside the PCB and regards to the housing, too (refer to 6.5). -
