Suunto’s subsequent coronary heart fee belt clears the FCC

Suunto’s unreleased SHRM2 coronary heart fee monitor has cleared the FCC, confirming that it’s a chest strap with Bluetooth Low Energy, a replaceable CR2032 battery and 30-metre water resistance. It is similar machine we first uncovered in May, however the newest submitting fills in a number of vital gaps.

The FCC confirms it’s a chest strap

When we first reported on the Suunto SHRM2, the machine had appeared in Singapore’s IMDA database. That itemizing described it as a Bluetooth coronary heart fee monitor, however didn’t say whether or not Suunto was engaged on a standard chest strap or one thing worn elsewhere on the physique.

The FCC documents now settle that query. Suunto describes SHRM2 as a coronary heart fee belt within the testing materials, whereas the regulatory data is printed on a round battery cowl just like the one utilized by its present chest sensor.

The label confirms a replaceable CR2032 battery. Suunto’s present Smart Heart Rate Belt makes use of a smaller CR2025 cell and has an official battery life estimate of round 500 hours.

A CR2032 has extra capability, so longer battery life appears doubtless. The submitting doesn’t present an official runtime, although, and battery effectivity will even rely upon the brand new electronics and the way typically the sensor shops or transmits knowledge.

Water resistance is rated at 30 metres, or 100 ft. That matches Suunto’s present belt and makes swimming assist doubtless.

Bluetooth particulars and an earlier processor clue

SHRM2 makes use of Bluetooth Low Energy throughout the usual 2402 to 2480 MHz frequency vary. Testing covers each 1 Mbps and a pair of Mbps modes, suggesting Suunto has moved to a more moderen Bluetooth platform.

The paperwork don’t point out ANT+. That could imply the brand new belt will stay Bluetooth-only, however the public submitting shouldn’t be detailed sufficient to rule out further wi-fi modes earlier than the complete handbook seems.

There can also be no affirmation of simultaneous Bluetooth connections. Support for 2 or extra connections would permit the belt to ship coronary heart fee to a Suunto watch and one other machine, equivalent to fitness center tools or a coaching app, on the identical time.

An earlier clue from Nordic Semiconductor’s developer discussion board pointed to the nRF54L15 processor. References to SHRM2 appeared in software program construct paths linked to the chip, though the submitting has not confirmed that it sits contained in the machine.

What stays unknown

The exterior photographs, inside photographs and person handbook stay confidential till January 19, 2027. That date doesn’t essentially level to the launch, as Suunto can launch the paperwork earlier when it declares the product.

Suunto has already proven how rapidly one in all these regulatory discoveries can flip right into a completed product. The Suunto Core 2 appeared in FCC paperwork earlier than launching this week, so SHRM2 might also be additional alongside than the confidential submitting dates counsel.
